AutobahnHash

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.

Benchmarks

The following benchmarks were done on an Intel i7-9750H, to give an idea of the performance profile. These two benchmarks can help predict best- and worst-case performance.

Slices

The HighwayHash algorithm performs best on long slices of data:

Non-slice data

Worst-case performance can be predicted with non-slice data: struct Data(u8, u16, u32, u64);
