Constants

const SaltLength = 32

SaltLength is the number of bytes which should be used as salt in hashing functions

Variables

var ErrSaltLengthMismatch = fmt.Errorf("provided salt is not %d length", SaltLength)

ErrSaltLengthMismath is used when the provided salt does not match the expected SaltLength

Types

type Hasher

type Hasher interface {
	Hash64([]byte) uint64
}

Hasher implements different non cryptographic hashing functions

func NewMetroHasher

func NewMetroHasher(salt []byte) (Hasher, error)

NewMetroHasher returns a metro hasher that uses salt as a prefix to the bytes being summed

func NewMurmur3Hasher

func NewMurmur3Hasher(salt []byte) (Hasher, error)

NewMurmur3Hasher returns a Murmur3 hasher that uses salt as a prefix to the bytes being summed
