Crate autobahn_hash

A pure Rust implementation of HighwayHash.

A few highlights:

• No unsafe
• Fuzzed against the reference implementation
• Minimal crate with few required dependencies
• Portable to any SIMD instruction set (and reasonably fast without SIMD)

This crate requires the portable_simd nightly feature.

There are two optional features:

• std: enables RandomState
• multiversion: enables hash_64 and friends, which select the optimal instruction set at runtime
  • Adds the multiversion crate as a dependency
  • Also enables the std feature

Structs

• AutobahnHasher
  A hash instance.
• RandomStatestd
  Build AutobahnHashers with random keys.

Functions

• hash_64multiversion
  Hash a slice with the given key.
• hash_128multiversion
  Hash a slice with the given key.
• hash_256multiversion
  Hash a slice with the given key.
