Functions

func New32

func New32() hash.Hash32

func New64

func New64() hash.Hash64

func Sum128

func Sum128(data []byte) (h1 uint64, h2 uint64)

Sum128 returns the MurmurHash3 sum of data. It is equivalent to the following sequence (without the extra burden and the extra allocation):

hasher := New128()
hasher.Write(data)
return hasher.Sum128()

func Sum32

func Sum32(data []byte) uint32

Sum32 returns the MurmurHash3 sum of data. It is equivalent to the following sequence (without the extra burden and the extra allocation):

hasher := New32()
hasher.Write(data)
return hasher.Sum32()

func Sum64

func Sum64(data []byte) uint64

Sum64 returns the MurmurHash3 sum of data. It is equivalent to the following sequence (without the extra burden and the extra allocation):

hasher := New64()
hasher.Write(data)
return hasher.Sum64()

Types

type Hash128

type Hash128 interface {
	hash.Hash
	Sum128() (uint64, uint64)
}

Hack: the standard api doesn't define any Hash128 interface.

func New128

func New128() Hash128
