strsim-rs

Rust implementations of string similarity metrics:

• Hamming
• Levenshtein
• Optimal string alignment
• Damerau-Levenshtein
• Jaro and Jaro-Winkler - this implementation of Jaro-Winkler does not limit the common prefix length

Usage

extern crate strsim;

use strsim::{hamming, levenshtein, osa_distance, damerau_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_eq!(3, osa_distance("ac", "cba"));

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

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

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

Development

If you don't want to install Rust itself, you can run $ ./dev for a development CLI if you have Docker installed.
