# strsim-rs

Rust implementations of [string similarity metrics]. Best efforts will be made to stay up-to-date with Rust nightly. Currently includes:
  - [Hamming]
  - [Levenshtein]
  - [Jaro and Jaro-Winkler] - this implementation does not limit the common prefix length

### Installation

```toml
# Cargo.toml
[dependencies]
strsim = "0.1.0"
```

### Usage

```rust
extern crate strsim;

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

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

    assert!(0.392 - jaro("Friedrich Nietzsche", "Jean-Paul Sartre") < 0.001);
    
    assert!(0.911 - jaro_winkler("cheeseburger", "cheese fries") < 0.001);
}
```
