https://github.com/golang/protobuf
|
||||
This module
|
||||
([`github.com/golang/protobuf`](https://pkg.go.dev/mod/github.com/golang/protobuf))
|
||||
contains Go bindings for protocol buffers.
|
||||
|
||||
This package and the code it generates requires at least Go 1.9.
|
||||
It has been superseded by the
|
||||
[`google.golang.org/protobuf`](https://pkg.go.dev/mod/google.golang.org/protobuf)
|
||||
module, which contains an updated and simplified API,
|
||||
support for protobuf reflection, and many other improvements.
|
||||
We recommend that new code use the `google.golang.org/protobuf` module.
|
||||
|
||||
This software implements Go bindings for protocol buffers. For
|
||||
information about protocol buffers themselves, see
|
||||
https://developers.google.com/protocol-buffers/
|
||||
Versions v1.4 and later of `github.com/golang/protobuf` are implemented
|
||||
in terms of `google.golang.org/protobuf`.
|
||||
Programs which use both modules must use at least version v1.4 of this one.
|
||||
|
||||
## Installation ##
|
||||
See the
|
||||
[developer guide for protocol buffers in Go](https://developers.google.com/protocol-buffers/docs/gotutorial)
|
||||
for a general guide for how to get started using protobufs in Go.
|
||||
|
||||
To use this software, you must:
|
||||
- Install the standard C++ implementation of protocol buffers from
|
||||
https://developers.google.com/protocol-buffers/
|
||||
- Of course, install the Go compiler and tools from
|
||||
https://golang.org/
|
||||
See
|
||||
https://golang.org/doc/install
|
||||
for details or, if you are using gccgo, follow the instructions at
|
||||
https://golang.org/doc/install/gccgo
|
||||
- Grab the code from the repository and install the `proto` package.
|
||||
The simplest way is to run:
|
||||
```
|
||||
go get -u github.com/golang/protobuf/protoc-gen-go
|
||||
```
|
||||
The compiler plugin, `protoc-gen-go`, will be installed in `$GOPATH/bin`
|
||||
unless `$GOBIN` is set. It must be in your `$PATH` for the protocol
|
||||
compiler, `protoc`, to find it.
|
||||
- If you need a particular version of `protoc-gen-go` (e.g., to match your
|
||||
`proto` package version), one option is
|
||||
```shell
|
||||
GIT_TAG="v1.2.0" # change as needed
|
||||
go get -d -u github.com/golang/protobuf/protoc-gen-go
|
||||
git -C "$(go env GOPATH)"/src/github.com/golang/protobuf checkout $GIT_TAG
|
||||
go install github.com/golang/protobuf/protoc-gen-go
|
||||
```
|
||||
See
|
||||
[release note documentation](https://github.com/golang/protobuf/releases)
|
||||
for more information about individual releases of this project.
|
||||
|
||||
This software has two parts: a 'protocol compiler plugin' that
|
||||
generates Go source files that, once compiled, can access and manage
|
||||
protocol buffers; and a library that implements run-time support for
|
||||
encoding (marshaling), decoding (unmarshaling), and accessing protocol
|
||||
buffers.
|
||||
See
|
||||
[documentation for the next major revision](https://pkg.go.dev/mod/google.golang.org/protobuf)
|
||||
for more information about the purpose, usage, and history of this project.
|
||||
|
||||
There is support for gRPC in Go using protocol buffers.
|
||||
See the note at the bottom of this file for details.
|
||||

## Using protocol buffers with Go ##
|
||||
## Reporting issues
|
||||
|
||||
Once the software is installed, there are two steps to using it.
|
||||
First you must compile the protocol buffer definitions and then import
|
||||
them, with the support library, into your program.
|
||||
The issue tracker for this project
|
||||
[is located here](https://github.com/golang/protobuf/issues).
|
||||
|
||||
To compile the protocol buffer definition, run protoc with the --go_out
|
||||
parameter set to the directory you want to output the Go code to.
|
||||
Please report any issues with a sufficient description of the bug or feature
|
||||
request. Bug reports should ideally be accompanied by a minimal reproduction of
|
||||
the issue. Irreproducible bugs are difficult to diagnose and fix (and likely to
|
||||
be closed after some period of time). Bug reports must specify the version of
|
||||
the
|
||||
[Go protocol buffer module](https://github.com/protocolbuffers/protobuf-go/releases)
|
||||
and also the version of the
|
||||
[protocol buffer toolchain](https://github.com/protocolbuffers/protobuf/releases)
|
||||
being used.
|
||||
|
||||
protoc --go_out=. *.proto
|
||||
## Contributing
|
||||
|
||||
The generated files will be suffixed .pb.go. See the Test code below
|
||||
for an example using such a file.
|
||||
This project is open-source and accepts contributions. See the
|
||||
[contribution guide](https://github.com/golang/protobuf/blob/master/CONTRIBUTING.md)
|
||||
for more information.
|
||||
|
||||
## Packages and input paths ##
|
||||
## Compatibility
|
||||
|
||||
The protocol buffer language has a concept of "packages" which does not
|
||||
correspond well to the Go notion of packages. In generated Go code,
|
||||
each source `.proto` file is associated with a single Go package. The
|
||||
name and import path for this package is specified with the `go_package`
|
||||
proto option:
|
||||
This module and the generated code are expected to be stable over time. However,
|
||||
we reserve the right to make breaking changes without notice for the following
|
||||
reasons:
|
||||
|
||||
option go_package = "github.com/golang/protobuf/ptypes/any";
|
||||
|
||||
The protocol buffer compiler will attempt to derive a package name and
|
||||
import path if a `go_package` option is not present, but it is
|
||||
best to always specify one explicitly.
|
||||
|
||||
There is a one-to-one relationship between source `.proto` files and
|
||||
generated `.pb.go` files, but any number of `.pb.go` files may be
|
||||
contained in the same Go package.
|
||||
|
||||
The output name of a generated file is produced by replacing the
|
||||
`.proto` suffix with `.pb.go` (e.g., `foo.proto` produces `foo.pb.go`).
|
||||
However, the output directory is selected in one of two ways. Let
|
||||
us say we have `inputs/x.proto` with a `go_package` option of
|
||||
`github.com/golang/protobuf/p`. The corresponding output file may
|
||||
be:
|
||||
|
||||
- Relative to the import path:
|
||||
|
||||
```shell
|
||||
protoc --go_out=. inputs/x.proto
|
||||
# writes ./github.com/golang/protobuf/p/x.pb.go
|
||||
```
|
||||
|
||||
(This can work well with `--go_out=$GOPATH`.)
|
||||
|
||||
- Relative to the input file:
|
||||
|
||||
```shell
|
||||
protoc --go_out=paths=source_relative:. inputs/x.proto
|
||||
# generate ./inputs/x.pb.go
|
||||
```
|
||||
|
||||
## Generated code ##
|
||||
|
||||
The package comment for the proto library contains text describing
|
||||
the interface provided in Go for protocol buffers. Here is an edited
|
||||
version.
|
||||
|
||||
The proto package converts data structures to and from the
|
||||
wire format of protocol buffers. It works in concert with the
|
||||
Go source code generated for .proto files by the protocol compiler.
|
||||
|
||||
A summary of the properties of the protocol buffer interface
|
||||
for a protocol buffer variable v:
|
||||
|
||||
- Names are turned from camel_case to CamelCase for export.
|
||||
- There are no methods on v to set fields; just treat
|
||||
them as structure fields.
|
||||
- There are getters that return a field's value if set,
|
||||
and return the field's default value if unset.
|
||||
The getters work even if the receiver is a nil message.
|
||||
- The zero value for a struct is its correct initialization state.
|
||||
All desired fields must be set before marshaling.
|
||||
- A Reset() method will restore a protobuf struct to its zero state.
|
||||
- Non-repeated fields are pointers to the values; nil means unset.
|
||||
That is, optional or required field int32 f becomes F *int32.
|
||||
- Repeated fields are slices.
|
||||
- Helper functions are available to aid the setting of fields.
|
||||
Helpers for getting values are superseded by the
|
||||
GetFoo methods and their use is deprecated.
|
||||
msg.Foo = proto.String("hello") // set field
|
||||
- Constants are defined to hold the default values of all fields that
|
||||
have them. They have the form Default_StructName_FieldName.
|
||||
Because the getter methods handle defaulted values,
|
||||
direct use of these constants should be rare.
|
||||
- Enums are given type names and maps from names to values.
|
||||
Enum values are prefixed with the enum's type name. Enum types have
|
||||
a String method, and a Enum method to assist in message construction.
|
||||
- Nested groups and enums have type names prefixed with the name of
|
||||
the surrounding message type.
|
||||
- Extensions are given descriptor names that start with E_,
|
||||
followed by an underscore-delimited list of the nested messages
|
||||
that contain it (if any) followed by the CamelCased name of the
|
||||
extension field itself. HasExtension, ClearExtension, GetExtension
|
||||
and SetExtension are functions for manipulating extensions.
|
||||
- Oneof field sets are given a single field in their message,
|
||||
with distinguished wrapper types for each possible field value.
|
||||
- Marshal and Unmarshal are functions to encode and decode the wire format.
|
||||
|
||||
When the .proto file specifies `syntax="proto3"`, there are some differences:
|
||||
|
||||
- Non-repeated fields of non-message type are values instead of pointers.
|
||||
- Enum types do not get an Enum method.
|
||||
|
||||
Consider file test.proto, containing
|
||||
|
||||
```proto
|
||||
syntax = "proto2";
|
||||
package example;
|
||||
|
||||
enum FOO { X = 17; };
|
||||
|
||||
message Test {
|
||||
required string label = 1;
|
||||
optional int32 type = 2 [default=77];
|
||||
repeated int64 reps = 3;
|
||||
}
|
||||
```
|
||||
|
||||
To create and play with a Test object from the example package,
|
||||
|
||||
```go
|
||||
package main
|
||||
|
||||
import (
|
||||
"log"
|
||||
|
||||
"github.com/golang/protobuf/proto"
|
||||
"path/to/example"
|
||||
)
|
||||
|
||||
func main() {
|
||||
test := &example.Test{
|
||||
Label: proto.String("hello"),
|
||||
Type: proto.Int32(17),
|
||||
Reps: []int64{1, 2, 3},
|
||||
}
|
||||
data, err := proto.Marshal(test)
|
||||
if err != nil {
|
||||
log.Fatal("marshaling error: ", err)
|
||||
}
|
||||
newTest := &example.Test{}
|
||||
err = proto.Unmarshal(data, newTest)
|
||||
if err != nil {
|
||||
log.Fatal("unmarshaling error: ", err)
|
||||
}
|
||||
// Now test and newTest contain the same data.
|
||||
if test.GetLabel() != newTest.GetLabel() {
|
||||
log.Fatalf("data mismatch %q != %q", test.GetLabel(), newTest.GetLabel())
|
||||
}
|
||||
// etc.
|
||||
}
|
||||
```
|
||||
|
||||
## Parameters ##
|
||||
|
||||
To pass extra parameters to the plugin, use a comma-separated
|
||||
parameter list separated from the output directory by a colon:
|
||||
|
||||
protoc --go_out=plugins=grpc,import_path=mypackage:. *.proto
|
||||
|
||||
- `paths=(import | source_relative)` - specifies how the paths of
|
||||
generated files are structured. See the "Packages and imports paths"
|
||||
section above. The default is `import`.
|
||||
- `plugins=plugin1+plugin2` - specifies the list of sub-plugins to
|
||||
load. The only plugin in this repo is `grpc`.
|
||||
- `Mfoo/bar.proto=quux/shme` - declares that foo/bar.proto is
|
||||
associated with Go package quux/shme. This is subject to the
|
||||
import_prefix parameter.
|
||||
|
||||
The following parameters are deprecated and should not be used:
|
||||
|
||||
- `import_prefix=xxx` - a prefix that is added onto the beginning of
|
||||
all imports.
|
||||
- `import_path=foo/bar` - used as the package if no input files
|
||||
declare `go_package`. If it contains slashes, everything up to the
|
||||
rightmost slash is ignored.
|
||||
|
||||
## gRPC Support ##
|
||||
|
||||
If a proto file specifies RPC services, protoc-gen-go can be instructed to
|
||||
generate code compatible with gRPC (http://www.grpc.io/). To do this, pass
|
||||
the `plugins` parameter to protoc-gen-go; the usual way is to insert it into
|
||||
the --go_out argument to protoc:
|
||||
|
||||
protoc --go_out=plugins=grpc:. *.proto
|
||||
|
||||
## Compatibility ##
|
||||
|
||||
The library and the generated code are expected to be stable over time.
|
||||
However, we reserve the right to make breaking changes without notice for the
|
||||
following reasons:
|
||||
|
||||
- Security. A security issue in the specification or implementation may come to
|
||||
light whose resolution requires breaking compatibility. We reserve the right
|
||||
to address such security issues.
|
||||
- Unspecified behavior. There are some aspects of the Protocol Buffers
|
||||
specification that are undefined. Programs that depend on such unspecified
|
||||
behavior may break in future releases.
|
||||
- Specification errors or changes. If it becomes necessary to address an
|
||||
inconsistency, incompleteness, or change in the Protocol Buffers
|
||||
specification, resolving the issue could affect the meaning or legality of
|
||||
existing programs. We reserve the right to address such issues, including
|
||||
updating the implementations.
|
||||
- Bugs. If the library has a bug that violates the specification, a program
|
||||
that depends on the buggy behavior may break if the bug is fixed. We reserve
|
||||
the right to fix such bugs.
|
||||
- Adding methods or fields to generated structs. These may conflict with field
|
||||
names that already exist in a schema, causing applications to break. When the
|
||||
code generator encounters a field in the schema that would collide with a
|
||||
generated field or method name, the code generator will append an underscore
|
||||
to the generated field or method name.
|
||||
- Adding, removing, or changing methods or fields in generated structs that
|
||||
start with `XXX`. These parts of the generated code are exported out of
|
||||
necessity, but should not be considered part of the public API.
|
||||
- Adding, removing, or changing unexported symbols in generated code.
|
||||
* **Security:** A security issue in the specification or implementation may
|
||||
come to light whose resolution requires breaking compatibility. We reserve
|
||||
the right to address such issues.
|
||||
* **Unspecified behavior:** There are some aspects of the protocol buffer
|
||||
specification that are undefined. Programs that depend on unspecified
|
||||
behavior may break in future releases.
|
||||
* **Specification changes:** It may become necessary to address an
|
||||
inconsistency, incompleteness, or change in the protocol buffer
|
||||
specification, which may affect the behavior of existing programs. We
|
||||
reserve the right to address such changes.
|
||||
* **Bugs:** If a package has a bug that violates correctness, a program
|
||||
depending on the buggy behavior may break if the bug is fixed. We reserve
|
||||
the right to fix such bugs.
|
||||
* **Generated additions**: We reserve the right to add new declarations to
|
||||
generated Go packages of `.proto` files. This includes declared constants,
|
||||
variables, functions, types, fields in structs, and methods on types. This
|
||||
may break attempts at injecting additional code on top of what is generated
|
||||
by `protoc-gen-go`. Such practice is not supported by this project.
|
||||
* **Internal changes**: We reserve the right to add, modify, and remove
|
||||
internal code, which includes all unexported declarations, the
|
||||
[`generator`](https://pkg.go.dev/github.com/golang/protobuf/protoc-gen-go/generator)
|
||||
package, and all packages under
|
||||
[`internal`](https://pkg.go.dev/github.com/golang/protobuf/internal).
|
||||
|
||||
Any breaking changes outside of these will be announced 6 months in advance to
|
||||
protobuf@googlegroups.com.
|
||||
|
||||
You should, whenever possible, use generated code created by the `protoc-gen-go`
|
||||
tool built at the same commit as the `proto` package. The `proto` package
|
||||
declares package-level constants in the form `ProtoPackageIsVersionX`.
|
||||
Application code and generated code may depend on one of these constants to
|
||||
ensure that compilation will fail if the available version of the proto library
|
||||
is too old. Whenever we make a change to the generated code that requires newer
|
||||
library support, in the same commit we will increment the version number of the
|
||||
generated code and declare a new package-level constant whose name incorporates
|
||||
the latest version number. Removing a compatibility constant is considered a
|
||||
breaking change and would be subject to the announcement policy stated above.
|
||||
|
||||
The `protoc-gen-go/generator` package exposes a plugin interface,
|
||||
which is used by the gRPC code generation. This interface is not
|
||||
supported and is subject to incompatible changes without notice.

Equal returns true iff protocol buffers a and b are equal.

The arguments must both be pointers to protocol buffer structs.

Equality is defined in this way:

- Two messages are equal iff they are the same type,
|

corresponding fields are equal, unknown field sets
|

are equal, and extensions sets are equal.
|
||||
- Two set scalar fields are equal iff their values are equal.
|

If the fields are of a floating-point type, remember that

NaN != x for all x, including NaN. If the message is defined
|
||||
in a proto3 .proto file, fields are not "set"; specifically,
|
||||
zero length proto3 "bytes" fields are equal (nil == {}).
|
||||
- Two repeated fields are equal iff their lengths are the same,
|
||||
and their corresponding elements are equal. Note a "bytes" field,
|
||||
although represented by []byte, is not a repeated field and the
|
||||
rule for the scalar fields described above applies.
|
||||
- Two unset fields are equal.
|
||||
- Two unknown field sets are equal if their current
|
||||
encoded state is equal.
|
||||
- Two extension sets are equal iff they have corresponding
|
||||
elements that are pairwise equal.
|
||||
- Two map fields are equal iff their lengths are the same,

and they contain the same set of elements. Zero-length map
|

fields are equal.

/*
|
||||
Package proto converts data structures to and from the wire format of
|
||||
protocol buffers. It works in concert with the Go source code generated
|
||||
for .proto files by the protocol compiler.
|
||||
|
||||
A summary of the properties of the protocol buffer interface
|
||||
for a protocol buffer variable v:
|
||||
|
||||
- Names are turned from camel_case to CamelCase for export.
|
||||
- There are no methods on v to set fields; just treat
|
||||
them as structure fields.
|
||||
- There are getters that return a field's value if set,
|
||||
and return the field's default value if unset.
|
||||
The getters work even if the receiver is a nil message.
|
||||
- The zero value for a struct is its correct initialization state.
|
||||
All desired fields must be set before marshaling.
|
||||
- A Reset() method will restore a protobuf struct to its zero state.
|
||||
- Non-repeated fields are pointers to the values; nil means unset.
|
||||
That is, optional or required field int32 f becomes F *int32.
|
||||
- Repeated fields are slices.
|
||||
- Helper functions are available to aid the setting of fields.
|
||||
msg.Foo = proto.String("hello") // set field
|
||||
- Constants are defined to hold the default values of all fields that
|
||||
have them. They have the form Default_StructName_FieldName.
|
||||
Because the getter methods handle defaulted values,
|
||||
direct use of these constants should be rare.
|
||||
- Enums are given type names and maps from names to values.
|
||||
Enum values are prefixed by the enclosing message's name, or by the
|
||||
enum's type name if it is a top-level enum. Enum types have a String
|
||||
method, and a Enum method to assist in message construction.
|
||||
- Nested messages, groups and enums have type names prefixed with the name of
|
||||
the surrounding message type.
|
||||
- Extensions are given descriptor names that start with E_,
|
||||
followed by an underscore-delimited list of the nested messages
|
||||
that contain it (if any) followed by the CamelCased name of the
|
||||
extension field itself. HasExtension, ClearExtension, GetExtension
|
||||
and SetExtension are functions for manipulating extensions.
|
||||
- Oneof field sets are given a single field in their message,
|
||||
with distinguished wrapper types for each possible field value.
|
||||
- Marshal and Unmarshal are functions to encode and decode the wire format.
|
||||
|
||||
When the .proto file specifies `syntax="proto3"`, there are some differences:
|
||||
|
||||
- Non-repeated fields of non-message type are values instead of pointers.
|
||||
- Enum types do not get an Enum method.
|
||||
|
||||
The simplest way to describe this is to see an example.
|
||||
Given file test.proto, containing
|
||||
|
||||
package example;
|
||||
|
||||
enum FOO { X = 17; }
|
||||
|
||||
message Test {
|
||||
required string label = 1;
|
||||
optional int32 type = 2 [default=77];
|
||||
repeated int64 reps = 3;
|
||||
optional group OptionalGroup = 4 {
|
||||
required string RequiredField = 5;
|
||||
}
|
||||
oneof union {
|
||||
int32 number = 6;
|
||||
string name = 7;

}

|

// ====
|

// The JSON representation of an `Any` value uses the regular
|
||||
// representation of the deserialized, embedded message, with an
|
||||
// additional field `@type` which contains the type URL. Example:
|
||||
//
|
||||
// package google.profile;
|
||||
// message Person {
|
||||
// string first_name = 1;
|
||||
// string last_name = 2;
|
||||
// }
|
||||
//
|
||||
// {
|
||||
// "@type": "type.googleapis.com/google.profile.Person",
|
||||
// "firstName": <string>,
|
||||
// "lastName": <string>
|
||||
// }
|
||||
//
|
||||
// If the embedded message type is well-known and has a custom JSON
|
||||
// representation, that representation will be embedded adding a field
|
||||
// `value` which holds the custom JSON in addition to the `@type`
|
||||
// field. Example (for message [google.protobuf.Duration][]):
|
||||
//
|
||||
// {
|
||||
// "@type": "type.googleapis.com/google.protobuf.Duration",
|
||||
// "value": "1.212s"
|
||||
// }
|
||||
//
|
||||
type Any struct {
|
||||
// A URL/resource name that uniquely identifies the type of the serialized
|
||||
// protocol buffer message. This string must contain at least
|
||||
// one "/" character. The last segment of the URL's path must represent
|
||||
// the fully qualified name of the type (as in
|
||||
// `path/google.protobuf.Duration`). The name should be in a canonical form
|
||||
// (e.g., leading "." is not accepted).
|
||||
//
|
||||
// In practice, teams usually precompile into the binary all types that they
|
||||
// expect it to use in the context of Any. However, for URLs which use the
|
||||
// scheme `http`, `https`, or no scheme, one can optionally set up a type
|
||||
// server that maps type URLs to message definitions as follows:
|
||||
//
|
||||
// * If no scheme is provided, `https` is assumed.
|
||||
// * An HTTP GET on the URL must yield a [google.protobuf.Type][]
|
||||
// value in binary format, or produce an error.
|
||||
// * Applications are allowed to cache lookup results based on the
|
||||
// URL, or have them precompiled into a binary to avoid any
|
||||
// lookup. Therefore, binary compatibility needs to be preserved
|
||||
// on changes to types. (Use versioned type names to manage
|
||||
// breaking changes.)
|
||||
//
|
||||
// Note: this functionality is not currently available in the official
|
||||
// protobuf release, and it is not used for type URLs beginning with
|
||||
// type.googleapis.com.
|
||||
//
|
||||
// Schemes other than `http`, `https` (or the empty scheme) might be
|
||||
// used with implementation specific semantics.
|
||||
//

// `Any` contains an arbitrary serialized protocol buffer message along with a

|
||||
//
|
||||
// Protobuf library provides support to pack/unpack Any values in the form
|
||||
// of utility functions or additional generated methods of the Any type.
|
||||
//
|
||||
// Example 1: Pack and unpack a message in C++.
|
||||
//
|
||||
// Foo foo = ...;
|
||||
// Any any;
|
||||
// any.PackFrom(foo);
|

|

// ...
|

// }
|

//
|

// Example 2: Pack and unpack a message in Java.
|
||||
//
|
||||
// Foo foo = ...;
|
||||
// Any any = Any.pack(foo);
|
||||
// ...
|
||||
// if (any.is(Foo.class)) {
|
||||
// foo = any.unpack(Foo.class);
|
||||
// }
|
||||
//
|
||||
// Example 3: Pack and unpack a message in Python.
|
||||
//
|
||||
// foo = Foo(...)
|
||||
// any = Any()
|
||||
// any.Pack(foo)
|
||||
// ...
|
||||
// if any.Is(Foo.DESCRIPTOR):
|
||||
// any.Unpack(foo)
|
||||
// ...
|
||||
//
|
||||
// Example 4: Pack and unpack a message in Go
|
||||
//
|
||||
// foo := &pb.Foo{...}
|
||||
// any, err := ptypes.MarshalAny(foo)
|

//
|
||||
// The pack methods provided by protobuf library will by default use
|
||||
// 'type.googleapis.com/full.type.name' as the type URL and the unpack
|
||||
// methods only use the fully qualified type name after the last '/'
|
||||
// in the type URL, for example "foo.bar.com/x/y.z" will yield type
|
||||
// name "y.z".
|
||||
//
|
||||
//
|
||||
// JSON
|
||||
// ====
|
||||
// The JSON representation of an `Any` value uses the regular
|
||||
// representation of the deserialized, embedded message, with an
|
||||
// additional field `@type` which contains the type URL. Example:
|
||||
//
|
||||
// package google.profile;
|
||||
// message Person {
|
||||
// string first_name = 1;
|
||||
// string last_name = 2;
|
||||
// }
|
||||
//
|
||||
// {
|
||||
// "@type": "type.googleapis.com/google.profile.Person",
|
||||
// "firstName": <string>,
|
||||
// "lastName": <string>
|
||||
// }
|
||||
//
|
||||
// If the embedded message type is well-known and has a custom JSON
|
||||
// representation, that representation will be embedded adding a field
|
||||
// `value` which holds the custom JSON in addition to the `@type`
|
||||
// field. Example (for message [google.protobuf.Duration][]):
|
||||
//
|
||||
// {
|
||||
// "@type": "type.googleapis.com/google.protobuf.Duration",
|
||||
// "value": "1.212s"
|
||||
// }
|
||||
//
|
||||
message Any {
|
||||
// A URL/resource name that uniquely identifies the type of the serialized
|
||||
// protocol buffer message. This string must contain at least
|
||||
// one "/" character. The last segment of the URL's path must represent
|
||||
// the fully qualified name of the type (as in
|
||||
// `path/google.protobuf.Duration`). The name should be in a canonical form
|
||||
// (e.g., leading "." is not accepted).
|
||||
//
|
||||
// In practice, teams usually precompile into the binary all types that they
|
||||
// expect it to use in the context of Any. However, for URLs which use the
|
||||
// scheme `http`, `https`, or no scheme, one can optionally set up a type
|
||||
// server that maps type URLs to message definitions as follows:
|
||||
//
|
||||
// * If no scheme is provided, `https` is assumed.
|
||||
// * An HTTP GET on the URL must yield a [google.protobuf.Type][]
|
||||
// value in binary format, or produce an error.
|
||||
// * Applications are allowed to cache lookup results based on the
|
||||
// URL, or have them precompiled into a binary to avoid any
|
||||
// lookup. Therefore, binary compatibility needs to be preserved
|
||||
// on changes to types. (Use versioned type names to manage
|
||||
// breaking changes.)
|
||||
//
|
||||
// Note: this functionality is not currently available in the official
|
||||
// protobuf release, and it is not used for type URLs beginning with
|
||||
// type.googleapis.com.
|
||||
//
|
||||
// Schemes other than `http`, `https` (or the empty scheme) might be
|
||||
// used with implementation specific semantics.
|

//

// # JSON Mapping
|

|
||||
// [RFC 3339](https://www.ietf.org/rfc/rfc3339.txt) format. That is, the
|
||||
// format is "{year}-{month}-{day}T{hour}:{min}:{sec}[.{frac_sec}]Z"

// where {year} is always expressed using four digits while {month}, {day},
|
||||
// {hour}, {min}, and {sec} are zero-padded to two digits each. The fractional
|
||||
// seconds, which can go up to 9 digits (i.e. up to 1 nanosecond resolution),
|
||||
// are optional. The "Z" suffix indicates the timezone ("UTC"); the timezone
|
||||
// is required. A proto3 JSON serializer should always use UTC (as indicated by
|
||||
// "Z") when printing the Timestamp type and a proto3 JSON parser should be
|
||||
// able to accept both UTC and other timezones (as indicated by an offset).
|
||||
//
|
||||
// For example, "2017-01-15T01:30:15.01Z" encodes 15.01 seconds past
|
||||
// 01:30 UTC on January 15, 2017.
|
||||
//
|
||||
// In JavaScript, one can convert a Date object to this format using the
|
||||
// standard
|
||||
// [toISOString()](https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Global_Objects/Date/toISOString)

||||
// the time format spec '%Y-%m-%dT%H:%M:%S.%fZ'. Likewise, in Java, one can use

||||
// gettimeofday(&tv, NULL);
|
||||
//
|
||||
// Timestamp timestamp;

// timestamp.set_seconds(tv.tv_sec);
|
||||
// timestamp.set_nanos(tv.tv_usec * 1000);

// Example 3: Compute Timestamp from Win32 `GetSystemTimeAsFileTime()`.

//
|

// FILETIME ft;

// long millis = System.currentTimeMillis();
|
||||
//
|

// # JSON Mapping
|
||||
//
|
||||
// In JSON format, the Timestamp type is encoded as a string in the
|
||||
// [RFC 3339](https://www.ietf.org/rfc/rfc3339.txt) format. That is, the
|
||||
// format is "{year}-{month}-{day}T{hour}:{min}:{sec}[.{frac_sec}]Z"
|
||||
// where {year} is always expressed using four digits while {month}, {day},
|
||||
// {hour}, {min}, and {sec} are zero-padded to two digits each. The fractional
|
||||
// seconds, which can go up to 9 digits (i.e. up to 1 nanosecond resolution),
|
||||
// are optional. The "Z" suffix indicates the timezone ("UTC"); the timezone
|
||||
// is required. A proto3 JSON serializer should always use UTC (as indicated by
|
||||
// "Z") when printing the Timestamp type and a proto3 JSON parser should be
|
||||
// able to accept both UTC and other timezones (as indicated by an offset).
|
||||
//
|
||||
// For example, "2017-01-15T01:30:15.01Z" encodes 15.01 seconds past
|
||||
// 01:30 UTC on January 15, 2017.
|
||||
//
|
||||
// In JavaScript, one can convert a Date object to this format using the

# Go support for Protocol Buffers
|
||||
|
||||
[![Go Reference](https://pkg.go.dev/badge/google.golang.org/protobuf.svg)](https://pkg.go.dev/google.golang.org/protobuf)
|
||||
[![Build Status](https://travis-ci.org/protocolbuffers/protobuf-go.svg?branch=master)](https://travis-ci.org/protocolbuffers/protobuf-go)
|
||||
|
||||
This project hosts the Go implementation for
|
||||
[protocol buffers](https://developers.google.com/protocol-buffers), which is a
|
||||
language-neutral, platform-neutral, extensible mechanism for serializing
|
||||
structured data. The protocol buffer language is a language for specifying the
|
||||
schema for structured data. This schema is compiled into language specific
|
||||
bindings. This project provides both a tool to generate Go code for the
|
||||
protocol buffer language, and also the runtime implementation to handle
|
||||
serialization of messages in Go. See the
|
||||
[protocol buffer developer guide](https://developers.google.com/protocol-buffers/docs/overview)
|
||||
for more information about protocol buffers themselves.
|
||||
|
||||
This project is comprised of two components:
|
||||
|
||||
* Code generator: The
|
||||
[`protoc-gen-go`](https://pkg.go.dev/google.golang.org/protobuf/cmd/protoc-gen-go)
|
||||
tool is a compiler plugin to `protoc`, the protocol buffer compiler. It
|
||||
augments the `protoc` compiler so that it knows how to
|
||||
[generate Go specific code for a given `.proto` file](https://developers.google.com/protocol-buffers/docs/reference/go-generated).
|
||||
|
||||
* Runtime library: The
|
||||
[`protobuf`](https://pkg.go.dev/mod/google.golang.org/protobuf) module
|
||||
contains a set of Go packages that form the runtime implementation of
|
||||
protobufs in Go. This provides the set of interfaces that
|
||||
[define what a message is](https://pkg.go.dev/google.golang.org/protobuf/reflect/protoreflect)
|
||||
and functionality to serialize message in various formats (e.g.,
|
||||
[wire](https://pkg.go.dev/google.golang.org/protobuf/proto),
|
||||
[JSON](https://pkg.go.dev/google.golang.org/protobuf/encoding/protojson),
|
||||
and
|
||||
[text](https://pkg.go.dev/google.golang.org/protobuf/encoding/prototext)).
|
||||
|
||||
See the
|
||||
[developer guide for protocol buffers in Go](https://developers.google.com/protocol-buffers/docs/gotutorial)
|
||||
for a general guide for how to get started using protobufs in Go.
|
||||
|
||||
This project is the second major revision of the Go protocol buffer API
|
||||
implemented by the
|
||||
[`google.golang.org/protobuf`](https://pkg.go.dev/mod/google.golang.org/protobuf)
|
||||
module. The first major version is implemented by the
|
||||
[`github.com/golang/protobuf`](https://pkg.go.dev/mod/github.com/golang/protobuf)
|
||||
module.
|
||||

## Reporting issues
|
||||
|
||||
The issue tracker for this project is currently located at
|
||||
[golang/protobuf](https://github.com/golang/protobuf/issues).
|
||||
|
||||
Please report any issues there with a sufficient description of the bug or
|
||||
feature request. Bug reports should ideally be accompanied by a minimal
|
||||
reproduction of the issue. Irreproducible bugs are difficult to diagnose and fix
|
||||
(and likely to be closed after some period of time). Bug reports must specify
|
||||
the version of the
|
||||
[Go protocol buffer module](https://github.com/protocolbuffers/protobuf-go/releases)
|
||||
and also the version of the
|
||||
[protocol buffer toolchain](https://github.com/protocolbuffers/protobuf/releases)
|
||||
being used.

## Contributing
|
||||
|
||||
This project is open-source and accepts contributions. See the
|
||||
[contribution guide](https://github.com/protocolbuffers/protobuf-go/blob/master/CONTRIBUTING.md)
|
||||
for more information.
|
||||
|
||||
## Compatibility
|
||||
|
||||
This module and the generated code are expected to be stable over time. However,
|
||||
we reserve the right to make breaking changes without notice for the following
|
||||
reasons:
|
||||
|
||||
* **Security:** A security issue in the specification or implementation may
|
||||
come to light whose resolution requires breaking compatibility. We reserve
|
||||
the right to address such issues.
|
||||
* **Unspecified behavior:** There are some aspects of the protocol buffer
|
||||
specification that are undefined. Programs that depend on unspecified
|
||||
behavior may break in future releases.
|
||||
* **Specification changes:** It may become necessary to address an
|
||||
inconsistency, incompleteness, or change in the protocol buffer
|
||||
specification, which may affect the behavior of existing programs. We
|
||||
reserve the right to address such changes.
|
||||
* **Bugs:** If a package has a bug that violates correctness, a program
|
||||
depending on the buggy behavior may break if the bug is fixed. We reserve
|
||||
the right to fix such bugs.
|
||||
* **Generated additions**: We reserve the right to add new declarations to
|
||||
generated Go packages of `.proto` files. This includes declared constants,
|
||||
variables, functions, types, fields in structs, and methods on types. This
|
||||
may break attempts at injecting additional code on top of what is generated
|
||||
by `protoc-gen-go`. Such practice is not supported by this project.
|
||||
* **Internal changes**: We reserve the right to add, modify, and remove
|
||||
internal code, which includes all unexported declarations, the
|
||||
[`protoc-gen-go/internal_gengo`](https://pkg.go.dev/google.golang.org/protobuf/cmd/protoc-gen-go/internal_gengo)
|
||||
package, the
|
||||
[`runtime/protoimpl`](https://pkg.go.dev/google.golang.org/protobuf/runtime/protoimpl?tab=doc)
|
||||
package, and all packages under
|
||||
[`internal`](https://pkg.go.dev/google.golang.org/protobuf/internal).
|
||||
|
||||
Any breaking changes outside of these will be announced 6 months in advance to
|
||||
[protobuf@googlegroups.com](https://groups.google.com/forum/#!forum/protobuf).
|
||||
|
||||
Users should use generated code produced by a version of
|
||||
[`protoc-gen-go`](https://pkg.go.dev/google.golang.org/protobuf/cmd/protoc-gen-go)
|
||||
that is identical to the runtime version provided by the
|
||||
[protobuf module](https://pkg.go.dev/mod/google.golang.org/protobuf). This
|
||||
project promises that the runtime remains compatible with code produced by a
|
||||
version of the generator that is no older than 1 year from the version of the
|
||||
runtime used, according to the release dates of the minor version. Generated
|
||||
code is expected to use a runtime version that is at least as new as the
|
||||
generator used to produce it. Generated code contains references to
|
||||
[`protoimpl.EnforceVersion`](https://pkg.go.dev/google.golang.org/protobuf/runtime/protoimpl?tab=doc#EnforceVersion)
|
||||
to statically ensure that the generated code and runtime do not drift
|
||||
sufficiently far apart.
|
||||
|
||||
## Historical legacy
|
||||
|
||||
This project is the second major revision
|
||||
([released in 2020](https://blog.golang.org/a-new-go-api-for-protocol-buffers))
|
||||
of the Go protocol buffer API implemented by the
|
||||
[`google.golang.org/protobuf`](https://pkg.go.dev/mod/google.golang.org/protobuf)
|
||||
module. The first major version
|
||||
([released publicly in 2010](https://blog.golang.org/third-party-libraries-goprotobuf-and))
|
||||
is implemented by the
|
||||
[`github.com/golang/protobuf`](https://pkg.go.dev/mod/github.com/golang/protobuf)
|
||||
module.
|
||||
|
||||
The first version predates the release of Go 1 by several years. It has a long
|
||||
history as one of the first core pieces of infrastructure software ever written
|
||||
in Go. As such, the Go protobuf project was one of many pioneers for determining
|
||||
what the Go language should even look like and what would eventually be
|
||||
considered good design patterns and “idiomatic” Go (by simultaneously being
|
||||
both positive and negative examples of it).
|
||||
|
||||
Consider the changing signature of the `proto.Unmarshal` function as an example
|
||||
of Go language and library evolution throughout the life of this project:
|
||||
|
||||
```go
|
||||
// 2007/09/25 - Conception of Go
|
||||
|
||||
// 2008/11/12
|
||||
export func UnMarshal(r io.Read, pb_e reflect.Empty) *os.Error
|
||||
|
||||
// 2008/11/13
|
||||
export func UnMarshal(buf *[]byte, pb_e reflect.Empty) *os.Error
|
||||
|
||||
// 2008/11/24
|
||||
export func UnMarshal(buf *[]byte, pb_e interface{}) *os.Error
|
||||
|
||||
// 2008/12/18
|
||||
export func UnMarshal(buf []byte, pb_e interface{}) *os.Error
|
||||
|
||||
// 2009/01/20
|
||||
func UnMarshal(buf []byte, pb_e interface{}) *os.Error
|
||||
|
||||
// 2009/04/17
|
||||
func UnMarshal(buf []byte, pb_e interface{}) os.Error
|
||||
|
||||
// 2009/05/22
|
||||
func Unmarshal(buf []byte, pb_e interface{}) os.Error
|
||||
|
||||
// 2011/11/03
|
||||
func Unmarshal(buf []byte, pb_e interface{}) error
|
||||
|
||||
// 2012/03/28 - Release of Go 1
|
||||
|
||||
// 2012/06/12
|
||||
func Unmarshal(buf []byte, pb Message) error
|
||||
```
|
||||
|
||||
These changes demonstrate the difficulty of determining what the right API is
|
||||
for any new technology. It takes time multiplied by many users to determine what
|
||||
is best; even then, “best” is often still somewhere over the horizon.
|
||||
|
||||
The change on June 6th, 2012 added a degree of type-safety to Go protobufs by
|
||||
declaring a new interface that all protobuf messages were required to implement:
|
||||
|
||||
```go
|
||||
type Message interface {
|
||||
Reset()
|
||||
String() string
|
||||
ProtoMessage()
|
||||
}
|
||||
```
|
||||
|
||||
This interface reduced the set of types that can be passed to `proto.Unmarshal`
|
||||
from the universal set of all possible Go types to those with a special
|
||||
`ProtoMessage` marker method. The intention of this change is to limit the
|
||||
protobuf API to only operate on protobuf data types (i.e., protobuf messages).
|
||||
For example, there is no sensible operation if a Go channel were passed to the
|
||||
protobuf API as a channel cannot be serialized. The restricted interface would
|
||||
prevent that.
|
||||
|
||||
This interface does not behaviorally describe what a protobuf message is, but
|
||||
acts as a marker with an undocumented expectation that protobuf messages must be
|
||||
a Go struct with a specific layout of fields with formatted tags. This
|
||||
expectation is not statically enforced by the Go language, for it is an
|
||||
implementation detail checked dynamically at runtime using Go reflection. Back
|
||||
in 2012, the only types with this marker were those generated by
|
||||
`protoc-gen-go`. Since `protoc-gen-go` would always generate messages with the
|
||||
proper layout of fields, this was deemed an acceptable and dramatic improvement
|
||||
over `interface{}`.
|
||||
|
||||
Over the next 10 years,
|
||||
[use of Go would skyrocket](https://blog.golang.org/10years) and use of
|
||||
protobufs in Go would skyrocket as well. With increased popularity also came
|
||||
more diverse usages and requirements for Go protobufs and an increased number of
|
||||
custom `proto.Message` implementations that were not generated by
|
||||
`protoc-gen-go`.
|
||||
|
||||
The increasingly diverse ecosystem of Go types implementing the `proto.Message`
|
||||
interface led to incompatibilities, which often occurred when:
|
||||
|
||||
* **Passing custom `proto.Message` types to the protobuf APIs**: A concrete
|
||||
message implementation might work with some top-level functions (e.g.,
|
||||
`proto.Marshal`), but cause others (e.g., `proto.Equal`) to choke and panic.
|
||||
This occurs because the type only had partial support for being an actual
|
||||
message by only implementing the `proto.Marshaler` interface or having
|
||||
malformed struct field tags that happened to work with one function, but not
|
||||
another.
|
||||
|
||||
* **Using Go reflection on any `proto.Message` types**: A common desire is to
|
||||
write general-purpose code that operates on any protobuf message. For
|
||||
example, a microservice might want to populate a `trace_id` field if it is
|
||||
present in a message. To accomplish this, one would use Go reflection to
|
||||
introspect the message type, and assume it were a pointer to a Go struct
|
||||
with a field named `TraceId` (as would be commonly produced by
|
||||
`protoc-gen-go`). If the concrete message type did not match this
|
||||
expectation, it either failed to work or even resulted in a panic. Such was
|
||||
the case for concrete message types that might be backed by a Go map instead
|
||||
of a Go struct.
|
||||
|
||||
Both of these issues are solved by following the idiom that _interfaces should
|
||||
describe behavior, not data_. This means that the interface itself should
|
||||
provide sufficient functionality through its methods that users can introspect
|
||||
and interact with all aspects of a protobuf message through a principled API.
|
||||
This feature is called _protobuf reflection_. Just as how Go reflection provides
|
||||
an API for programmatically interacting with any arbitrary Go value, protobuf
|
||||
reflection provides an API for programmatically interacting with any arbitrary
|
||||
protobuf message.
|
||||
|
||||
Since an interface cannot be extended in a backwards compatible way, this
|
||||
suggested the need for a new major version that defines a new `proto.Message`
|
||||
interface:
|
||||
|
||||
```go
|
||||
type Message interface {
|
||||
ProtoReflect() protoreflect.Message
|
||||
}
|
||||
```
|
||||
|
||||
The new
|
||||
[`proto.Message`](https://pkg.go.dev/google.golang.org/protobuf/proto?tab=doc#Message)
|
||||
interface contains a single `ProtoReflect` method that returns a
|
||||
[`protoreflect.Message`](https://pkg.go.dev/google.golang.org/protobuf/reflect/protoreflect?tab=doc#Message),
|
||||
which is a reflective view over a protobuf message. In addition to making a
|
||||
breaking change to the `proto.Message` interface, we took this opportunity to
|
||||
cleanup the supporting functionality that operate on a `proto.Message`, split up
|
||||
complicated functionality apart into manageable packages, and to hide
|
||||
implementation details away from the public API.
|
||||
|
||||
The goal for this major revision is to improve upon all the benefits of, while
|
||||
addressing all the shortcomings of the old API. We hope that it will serve the
|
||||
Go ecosystem well for the next 10 years and beyond.

|
||||
// resolve a dependency, which is information that must be provided separately
|

// space and time efficient way. Thus, we store them as a flattened list of
|
||||
// objects where the serialization order from the tree-based form is important.
|
||||
//
|
||||
// The "flattened ordering" is defined as a tree traversal of all enum, message,

// extension, and service declarations using the following algorithm:

//
|

// def VisitFileDecls(fd):
|

// for e in fd.Enums: yield e

// for m in md.Messages: yield m
|
||||
// for x in md.Extensions: yield x
|
||||
// for m in md.Messages: yield from VisitMessageDecls(m)
|
||||
//
|

// declaration within each node before traversing into sub-declarations

// that children themselves may have.
