xxhash
VENDORED: Go to github.com/cespare/xxhash for original package.
xxhash is a Go implementation of the 64-bit xxHash algorithm, XXH64. This is a high-quality hashing algorithm that is much faster than anything in the Go standard library.
This package provides a straightforward API:
func Sum64(b []byte) uint64
func Sum64String(s string) uint64
type Digest struct{ ... }
func New() *Digest
The Digest type implements hash.Hash64. Its key methods are:
func (*Digest) Write([]byte) (int, error)
func (*Digest) WriteString(string) (int, error)
func (*Digest) Sum64() uint64
This implementation provides a fast pure-Go implementation and an even faster assembly implementation for amd64.
Benchmarks
Here are some quick benchmarks comparing the pure-Go and assembly implementations of Sum64.
