Functions

func CrcSetAlg

func CrcSetAlg(alg uint8)

CrcSetAlg allow or disallow use of SSE4.2 instrinsics for CRC32 hash calculation. Specify OR of declared Crc32* flags.

func CrcUpdate

func CrcUpdate(data []byte, acc uint32) uint32

CrcUpdate calculate CRC32 hash on user-supplied byte array.

func NewCrcHash

func NewCrcHash(seed uint32, complement bool) hash.Hash32

NewCrcHash creates new hash.Hash32 implemented on top of CrcUpdate. If complement is true then accumulator argument is complemented to 1 along with the output. This gives identical output as native Go crc32's implementation.
