Functions ¶

func Sum64 ¶

func Sum64(b []byte) uint64

Sum64 computes the 64-bit xxHash digest of b.

Types ¶

type Digest ¶

type Digest struct {
	// contains filtered or unexported fields
}

Digest implements hash.Hash64.

func New ¶

func New() *Digest

New creates a new Digest that computes the 64-bit xxHash algorithm.

func (*Digest) BlockSize ¶

func (d *Digest) BlockSize() int

BlockSize always returns 32 bytes.

func (*Digest) MarshalBinary ¶

func (d *Digest) MarshalBinary() ([]byte, error)

MarshalBinary implements the encoding.BinaryMarshaler interface.

func (*Digest) Reset ¶

func (d *Digest) Reset()

Reset clears the Digest's state so that it can be reused.

func (*Digest) Size ¶

func (d *Digest) Size() int

Size always returns 8 bytes.

func (*Digest) Sum ¶

func (d *Digest) Sum(b []byte) []byte

Sum appends the current hash to b and returns the resulting slice.

func (*Digest) Sum64 ¶

func (d *Digest) Sum64() uint64

Sum64 returns the current hash.

func (*Digest) UnmarshalBinary ¶

func (d *Digest) UnmarshalBinary(b []byte) error

UnmarshalBinary implements the encoding.BinaryUnmarshaler interface.

func (*Digest) Write ¶

func (d *Digest) Write(b []byte) (n int, err error)

Write adds more data to d. It always returns len(b), nil.
