murmur2-go

Go implementation of MurmurHash2, based on the work by Austin Appleby. This repo was forked to add go modules, a more modern test suite (though still lacking in rigour), and a ci pipeline to ensure build + test passes.

Usage

Specified minimum version of go is v1.22.

$ go get github.com/yarefs/murmur2-go
