type Hash

type Hash interface {
    // Write (via the embedded io.Writer interface) adds more data to the running hash.
    // It never returns an error.
    io.Writer

    // Sum appends the current hash to b and returns the resulting slice.
    // It does not change the underlying hash state.
    Sum(b []byte) []byte

    // Reset resets the Hash to its initial state.
    Reset()

    // Size returns the number of bytes Sum will return.
    Size() int

    // BlockSize returns the hash's underlying block size.
    // The Write method must be able to accept any amount
    // of data, but it may operate more efficiently if all writes
    // are a multiple of the block size.
    BlockSize() int
}

Hash is the common interface implemented by all hash functions.

type Hash32

type Hash32 interface {
    Hash
    Sum32() uint32
}

Hash32 is the common interface implemented by all 32-bit hash functions.

type Hash64

type Hash64 interface {
    Hash
    Sum64() uint64
}

Hash64 is the common interface implemented by all 64-bit hash functions.
