type Hash Uses

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

    // 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.

    // 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 Uses

type Hash32 interface {
    Sum32() uint32

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

type Hash64 Uses

type Hash64 interface {
    Sum64() uint64

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


adler32Package adler32 implements the Adler-32 checksum.
crc32Package crc32 implements the 32-bit cyclic redundancy check, or CRC-32, checksum.
crc64Package crc64 implements the 64-bit cyclic redundancy check, or CRC-64, checksum.
fnvPackage fnv implements FNV-1 and FNV-1a, non-cryptographic hash functions created by Glenn Fowler, Landon Curt Noll, and Phong Vo.
