Max defines the maximum size of a hash value.

Functions

func ReuseSequenceHasher

func ReuseSequenceHasher(v *Sequence)

ReuseSequenceHasher returns the given sequential hash object to a pool ready for reuse by subsequent calls to NewSequenceHasher.

Types

type Hasher

type Hasher interface {
	Hash() Value // Hash returns a hash value for the object.
}

Hasher is the interface hashable objects should satisfy.

type Sequence
