// Package triegen implements a code generator for a trie for associating
// unsigned integer values with UTF-8 encoded runes.
//
// Many of the go.text packages use tries for storing per-rune information. A
// trie is especially useful if many of the runes have the same value. If this
// is the case, many blocks can be expected to be shared allowing for
// information on many runes to be stored in little space.
//
// As most of the lookups are done directly on []byte slices, the tries use the
// UTF-8 bytes directly for the lookup. This saves a conversion from UTF-8 to
// runes and contributes a little bit to better performance. It also naturally
// provides a fast path for ASCII.
//
// Space is also an issue. There are many code points defined in Unicode and as
// a result tables can get quite large. So every byte counts. The triegen
// package automatically chooses the smallest integer values to represent the
// tables. Compacters allow further compression of the trie by allowing for
// alternative representations of individual trie blocks.
//
// triegen allows generating multiple tries as a single structure. This is
// useful when, for example, one wants to generate tries for several languages
// that have a lot of values in common. Some existing libraries for
// internationalization store all per-language data as a dynamically loadable
// chunk. The go.text packages are designed with the assumption that the user
// typically wants to compile in support for all supported languages, in line
// with the approach common to Go to create a single standalone binary. The
// multi-root trie approach can give significant storage savings in this
// scenario.
//
// triegen generates both tables and code. The code is optimized to use the
// automatically chosen data types. The following code is generated for a Trie
// or multiple Tries named "foo":
// - type fooTrie
// The trie type.
//
// - func newFooTrie(x int) *fooTrie
// Trie constructor, where x is the index of the trie passed to Gen.
//
// - func (t *fooTrie) lookup(s []byte) (v uintX, sz int)
// The lookup method, where uintX is automatically chosen.
//
// - func lookupString, lookupUnsafe and lookupStringUnsafe
// Variants of the above.
//
// - var fooValues and fooIndex and any tables generated by Compacters.
// The core trie data.
//
// - var fooTrieHandles
// Indexes of starter blocks in case of multiple trie roots.
//
// It is recommended that users test the generated trie by checking the returned
// value for every rune. Such exhaustive tests are possible as the the number of
// runes in Unicode is limited.
package triegen // import "golang.org/x/text/internal/triegen"
// TODO: Arguably, the internally optimized data types would not have to be
// exposed in the generated API. We could also investigate not generating the
