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 Verify 

func Verify(
	payload codec.ThriftObject,
	checksum Checksum,
) error

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

Types

type Checksum 

type Checksum struct {
	// Version represents version of the payload from
	Version int
	// which this checksum was derived
	Flavor Flavor
	// Value is the checksum value
	Value []byte
}

Checksum represents a checksum value along with associated metadata

func GenerateCRC32 

func GenerateCRC32(
	payload codec.ThriftObject,
	payloadVersion int,
) (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

type Flavor 

type Flavor int

Flavor is an enum type that represents the type of checksum 

const (
	// FlavorUnknown represents an unknown/uninitialized checksum flavor
	FlavorUnknown Flavor = iota
	// FlavorIEEECRC32OverThriftBinary represents crc32 checksum generated over thriftRW serialized payload
	FlavorIEEECRC32OverThriftBinary
)

func (Flavor) IsValid 

func (f Flavor) IsValid() bool

IsValid returns true if the checksum flavor is valid
