Module spatium::edit_based::hamming

Hamming implementation

Hamming distance

The Hamming distance between two strings of equal length is the number of positions at which two strings are different.

Examples

use spatium::edit_based::hamming;

let alg = hamming::Default::default();
let x = [1, 2, 3];
let y = [1, 2, 4];
let distance = alg.distance(&x, &y).unwrap();
assert_eq!(distance, 1.0);

// On &str.
let x = "Hello-МИР";
let y = "Hello-ПИР";
let xc = x.chars().collect::<Vec<char>>();
let yc = y.chars().collect::<Vec<char>>();
let distance = alg.distance(&xc, &yc).unwrap();
assert_eq!(distance, 1.0);

// With normaliztion (normalized distance = distance / x.len())
let alg = hamming::Default::default().normalize_result(true);
let x = [1, 2, 3];
let y = [1, 2, 4];
let distance = alg.distance(&x, &y).unwrap();
assert_eq!(distance, 1.0 / 3.0);
