func New32() hash.Hash32

New32 returns a new 32-bit Jenkins's one_at_a_time hash.Hash.

Its Sum method will lay the value out in big-endian byte order.

type Sum32 uint32

Sum32 represents Jenkins's one_at_a_time hash.

Use the Sum32 type directly (as opposed to New32 below) to avoid allocations.

func (s *Sum32) BlockSize() int

BlockSize returns the hash's underlying block size.

func (s *Sum32) Reset()

Reset resets the hash to its initial state.

func (s *Sum32) Size() int

Size returns the number of bytes Sum will return.

func (s *Sum32) Sum(in []byte) []byte

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

It does not change the underlying hash state.

func (s *Sum32) Sum32() uint32

Sum32 returns the hash value

func (s *Sum32) Write(data []byte) (int, error)

Write adds more data to the running hash.

It never returns an error.
