Function anchorhash::fasthash

pub fn fasthash(k: u32, seed: u32) -> u32

A hash function producing a 32 bit hash for k, using seed as the initial hasher state.

This is a fallback implementation for platforms that do not support the _mm_crc32_u32 intrinsic. It makes use of the Fowler–Noll–Vo hash function which is extremely quick at hashing small amounts of data.
