A fast byte slice comparison library

The library is intended to provide a faster byte slice comparison than the standard library. Also raw string literals b"like this" are compareable this way. It also supports simd comparisons by enabling the feature simd_support in the Cargo.toml.

Example usage

use fastcmp::Compare;

let vec = vec![1, 2, 3, 4, 5];
assert!(vec.feq(&[1, 2, 3, 4, 5]));

Benchmarks

The benchmarking results for comparison of two &[u8] with a size of 256:

test fast_compare_equal    ... bench:          14 ns/iter (+/- 9) = 18285 MB/s
test fast_compare_unequal  ... bench:          14 ns/iter (+/- 0) = 18285 MB/s
test slice_compare_equal   ... bench:          35 ns/iter (+/- 29) = 7314 MB/s
test slice_compare_unequal ... bench:          37 ns/iter (+/- 3) = 6918 MB/s
