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.
