Types

type Hasher

type Hasher[K comparable] struct {
	// contains filtered or unexported fields
}

Hasher hashes values of type K. Uses runtime AES-based hashing.

func NewHasher

func NewHasher[K comparable]() Hasher[K]

NewHasher creates a new Hasher[K] with a random seed.

func NewSeed

func NewSeed[K comparable](h Hasher[K]) Hasher[K]

NewSeed returns a copy of |h| with a new hash seed.

func (Hasher[K]) Hash

func (h Hasher[K]) Hash(key K) uint64

Hash hashes |key|.

func (Hasher[K]) Hash2

func (h Hasher[K]) Hash2(key K) uintptr

Hash2 hashes |key| as more flexible uintptr.

type Hasher2

type Hasher2[K any] struct {
	// contains filtered or unexported fields
}

Hasher2 hashes values of type K. Uses runtime AES-based hashing.

func NewHasher2

func NewHasher2[K any]() Hasher2[K]

NewHasher2 creates a new Hasher2[K] with a random seed.

func NewSeed2

func NewSeed2[K comparable](h Hasher2[K]) Hasher2[K]

NewSeed2 returns a copy of |h| with a new hash seed.

func (Hasher2[K]) Hash

func (h Hasher2[K]) Hash(key K) uint64

Hash hashes |key|.

func (Hasher2[K]) Hash2

func (h Hasher2[K]) Hash2(key K) uintptr

Hash2 hashes |key| as more flexible uintptr.
