# vibrato

Vibrato is a fast implementation of tokenization (or morphological analysis) based on the viterbi algorithm.

## Examples

```rust
use std::fs::File;
use std::io::{BufRead, BufReader};

use vibrato::{Dictionary, Tokenizer};

let file = File::open("src/tests/resources/system.dic").unwrap();
let dict = Dictionary::read(BufReader::new(file)).unwrap();

let tokenizer = vibrato::Tokenizer::new(dict);
let mut worker = tokenizer.new_worker();

worker.reset_sentence("京都東京都").unwrap();
worker.tokenize();
assert_eq!(worker.num_tokens(), 2);

let t0 = worker.token(0);
assert_eq!(t0.surface(), "京都");
assert_eq!(t0.range_char(), 0..2);
assert_eq!(t0.range_byte(), 0..6);
assert_eq!(t0.feature(), "京都,名詞,固有名詞,地名,一般,*,*,キョウト,京都,*,A,*,*,*,1/5");

let t1 = worker.token(1);
assert_eq!(t1.surface(), "東京都");
assert_eq!(t1.range_char(), 2..5);
assert_eq!(t1.range_byte(), 6..15);
assert_eq!(t1.feature(), "東京都,名詞,固有名詞,地名,一般,*,*,トウキョウト,東京都,*,B,5/9,*,5/9,*");
```
