GTrie

Trie is the library that implements the trie.

Trie is a generic data structure, written Trie<T, U> where T is node key type and U is a value type.

Motivation

Trie may be faster than other data structures in some cases.

For example, Trie may be used as a replacement for HashMap in case of a dictionary where the number of words in dictionary is significantly less than number of different words in the input.

Usage

```rust use gtrie::Trie;

let mut t = Trie::new();

t.add("this".chars(), 1); t.add("trie".chars(), 2); t.add("contains".chars(), 3); t.add("a".chars(), 4); t.add("number".chars(), 5); t.add("of".chars(), 6); t.add("words".chars(), 7);

asserteq!(t.haskey("number".chars()), true); asserteq!(t.haskey("notexistingkey".chars()), false); asserteq!(t.getvalue("words".chars()), Some(7)); asserteq!(t.getvalue("none".chars()), None); ```
