Types

type Hasher

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

Hasher is a TupleHash instance.

func New128

func New128(outputSize int, customizationString []byte) *Hasher

New128 creates a new TupleHash128 instance with the specified output size (in bytes) and customization string.

func New256

func New256(outputSize int, customizationString []byte) *Hasher

New256 creates a new TupleHash256 instance with the specified output size (in bytes) and customization string.

func (*Hasher) Clone

func (h *Hasher) Clone() *Hasher

Clone creates a copy of an existing TupleHash instance.

func (*Hasher) Sum

func (h *Hasher) Sum(b []byte) []byte

Sum appends the current hash to b and returns the resulting slice. It does not change the underlying hash state.

func (*Hasher) Write

func (h *Hasher) Write(b []byte) (int, error)

Write writes the byte-encoded tuple b to the TupleHash.
