crypto/sha3/tuple_hash.go:10–19

TupleHash defines the interface to hash functions that support tuple input.

// TupleHash defines the interface to hash functions that
// support tuple input.
type TupleHash interface {
	hash.Hash

	// WriteItem writes length-prefixed item to the hash state.
	WriteItem(item []byte) (written int, err error)

	// WriteItemPrefix writes length prefix to the hash state
	// and must be followed by normal Write calls.
	WriteItemPrefix(length int) (written int, err error)
}

// TupleHashXOF defines the interface to hash functions that
// support tuple input with extensible output.
