### Usage
### Usage
```rust
extern crate strsim;

use strsim::{hamming, levenshtein, osa_distance, damerau_levenshtein, jaro,
             jaro_winkler};
             jaro_winkler};

fn main() {
    match hamming("hamming", "hammers") {
        Ok(distance) => assert_eq!(3, distance),
        Ok(distance) => assert_eq!(3, distance),
        Err(why) => panic!("{:?}", why)
    }

    assert_eq!(3, levenshtein("kitten", "sitting"));


    assert_eq!(3, osa_distance("ac", "cba"));

    assert_eq!(2, damerau_levenshtein("ac", "cba"));

    assert!((0.392 - jaro("Friedrich Nietzsche", "Jean-Paul Sartre")).abs() <
    assert!((0.392 - jaro("Friedrich Nietzsche", "Jean-Paul Sartre")).abs() <
            0.001);

    assert!((0.911 - jaro_winkler("cheeseburger", "cheese fries")).abs() <
            0.001);
}
}
```
