Function triple_accel::hamming::hamming

pub fn hamming(a: &[u8], b: &[u8]) -> u32

Returns the hamming distance between two strings using the best method.

The length of a and b must be the same. This will automatically fall back to a scalar alternative if AVX2 and SSE4.1 are not supported. Internally, this calls hamming_simd_parallel.

Arguments

• a - first string (slice)
• b - second string (slice)

Panics

• If the length of a does not equal the length of b.

Example

let dist = hamming(b"abc", b"abd");

assert!(dist == 1);
