Functions

func Decode

func Decode(dst, src []byte) (int, os.Error)

Decode decodes src into DecodedLen(len(src)) bytes, returning the actual number of bytes written to dst.

If Decode encounters invalid input, it returns an OddLengthInputError or an InvalidHexCharError.

func DecodeString

func DecodeString(s string) ([]byte, os.Error)

DecodeString returns the bytes represented by the hexadecimal string s.

func DecodedLen

func DecodedLen(x int) int

func Encode

func Encode(dst, src []byte) int

Encode encodes src into EncodedLen(len(src)) bytes of dst. As a convenience, it returns the number of bytes written to dst, but this value is always EncodedLen(len(src)). Encode implements hexadecimal encoding.

func EncodeToString

func EncodeToString(src []byte) string

EncodeToString returns the hexadecimal encoding of src.

func EncodedLen

func EncodedLen(n int) int

EncodedLen returns the length of an encoding of n source bytes.

Types

type InvalidHexCharError

type InvalidHexCharError byte

InvalidHexCharError results from finding an invalid character in a hex string.

func (InvalidHexCharError) String

func (e InvalidHexCharError) String() string

type OddLengthInputError

type OddLengthInputError struct{}

OddLengthInputError results from decoding an odd length slice.

func (OddLengthInputError) String

func (OddLengthInputError) String() string
