hamming

A crate to compute the Hamming weight of a vector and the Hamming distance between two efficiently.

Documentation, crates.io.

lib.rs:

A crate to count ones and xor bytes, fast (aka popcount, hamming weight and hamming distance).

Installation

Add this to your Cargo.toml:

[dependencies]
hamming = "0.1"

Examples

assert_eq!(hamming::weight(&[1, 0xFF, 1, 0xFF]), 1 + 8 + 1 + 8);
assert_eq!(hamming::distance(&[1, 0xFF], &[0xFF, 1]), 7 + 7);
