ZwoHash

ZwoHash implements a very fast hash algorithm optimized for the use in hash tables. It has low per-hash overhead, which is important when hashing small keys. It is non-cryptographic and deterministic and as such not suited for inserting untrusted user-provided input into hash tables, unless other denial of service countermeasures are taken. As such it covers the same use cases as rustc’s FxHash.
