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 Sum128WithSeed(data []byte, seed uint32) (h1 uint64, h2 uint64)

Sum128WithSeed returns the MurmurHash3 sum of data. It is equivalent to the following sequence (without the extra burden and the extra allocation):

hasher := New128WithSeed(seed)
hasher.Write(data)
return hasher.Sum128()

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

Hash128 represents a 128-bit hasher Hack: the standard api doesn't define any Hash128 interface.

func New128() Hash128

New128 returns a 128-bit hasher

func New128WithSeed(seed uint32) Hash128

New128WithSeed returns a 128-bit hasher set with explicit seed value
