Erlang NIF bindings for XXH3 hash functions implemented in Rust.
XXH3 is a new speed-optimized hash algorithm of the xxHash family of non-cryptographic hash functions, featuring:
- Improved speed for both small and large inputs
- True 64-bit and 128-bit outputs
- SIMD acceleration
- Improved 32-bit viability
Speed analysis methodology is explained here.
Erlang nif interface does not support passing bigints to the VM, so for 128-bit variants a 128-bit binary is passed, and then converted to a 128-bit integer in erlang.
Erlang wrapper functions are inlined to achieve maximum performance.
Data = <<"Test Data">>, Seed = 1, Secret = crypto:strong_rand_bytes(136), H64 = xxh3:hash64(Data), H64WithSeed = xxh3:hash64(Data, Seed), H64WithSecret = xxh3:hash64_with_secret(Data, Secret), H128 = xxh3:hash128(Data), H128WithSeed = xxh3:hash128(Data, Seed), H128WithSecret = xxh3:hash128_with_secret(Data, Secret).
data = "Test Data" seed = 1 secret = :crypto.strong_rand_bytes(136) h64 = :xxh3.hash64(data) h64_with_seed = :xxh3.hash64(data, seed) h64_with_secret = :xxh3.hash64_with_secret(data, secret) h128 = :xxh3.hash128(data) h128_with_seed = :xxh3.hash128(data, seed) h128_with_secret = :xxh3.hash128_with_secret(data, secret)
