you sure make popcount(prime)==32

wyhash crate is not wyhash itself. It depends on the skill of the translator and the wyhash version. wyhash has been improved significantly version by version. Also ahash should submit a PR to smhasher and play with ~100 other hash functions there.

I am also wondering whether ahash is faster. ahash is developed with rust. We need a head to head comparsion. However, it is not available in SMHasher package.

moew is not good at short keys. portability is also a concern
