Function distances::vectors::hamming

pub fn hamming<T: Int, U: UInt>(x: &[T], y: &[T]) -> U

Computes the Hamming distance between two vectors.

The Hamming distance is defined as the number of positions at which the corresponding elements are different.

See the crate::vectors module documentation for information on this function’s potentially unexpected behaviors

Arguments

• x: A slice of numbers.
• y: A slice of numbers.

Examples

use distances::vectors::hamming;

let x: Vec<u8> = vec![1, 2, 3];
let y: Vec<u8> = vec![1, 2, 3];

let distance: u8 = hamming(&x, &y);

assert_eq!(distance, 0);

let x: Vec<u8> = vec![1, 2, 3];
let y: Vec<u8> = vec![1, 2, 4];

let distance: u8 = hamming(&x, &y);

assert_eq!(distance, 1);
