Variables

var ErrMismatch = errors.New("checksum mismatch error")

ErrMismatch indicates a checksum verification failure due to a derived checksum not being equal to expected checksum

Functions

func GenerateCRC32

func GenerateCRC32(
	payload proto.Marshaler,
	payloadVersion int32,
) (*persistencespb.Checksum, error)

GenerateCRC32 generates an IEEE crc32 checksum on the serilized byte array of the given thrift object. The serialization proto used will be of type thriftRW

func Verify

func Verify(
	payload proto.Marshaler,
	checksum *persistencespb.Checksum,
) error

Verify verifies that the checksum generated from the given thrift object matches the specified expected checksum Return ErrMismatch when checksums mismatch
