# mojo-hash
A collection of hash functions implemented in Mojo.
## AHash
Original repo: https://github.com/tkaitchuck/aHash
Note: implements the fallback version (without AES-NI intrinsics use), uses folded multiply function without u128 support
## fnv1a
Original repo: https://github.com/ziglang/zig/blob/master/lib/std/hash/fnv.zig
Note: implements 32 and 64 bit variants
## fxhash
Original repo: https://github.com/cbreeden/fxhash/tree/master
Note: implements 32 and 64 bit variants
## Wyhash
Original repo: https://github.com/wangyi-fudan/wyhash
Note: `wymum` implemented as if `WYHASH_32BIT_MUM` is set and `WYHASH_CONDOM` not set. Little endian only.
## Benachmark
Collecets average hash function runtime in nanoseconds based on 7 different word collections. The average runtime is computed 20 times on each word collection, the fastest is kept as final result. Shows collision on full 32/64 bit space and 1024 mod (10 bit) space
