var ErrLength = errors.New("encoding/hex: odd length hex string")

ErrLength results from decoding an odd length slice.

Functions

func Decode

func Decode(dst, src []byte) (int, 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 error describing the failure.

func DecodeString

func DecodeString(s string) ([]byte, error)

DecodeString returns the bytes represented by the hexadecimal string s.

func DecodedLen

func DecodedLen(x int) int

func Dump

func Dump(data []byte) string

Dump returns a string that contains a hex dump of the given data. The format of the hex dump matches the output of `hexdump -C` on the command line.

func Dumper

func Dumper(w io.Writer) io.WriteCloser

Dumper returns a WriteCloser that writes a hex dump of all written data to w. The format of the dump matches the output of `hexdump -C` on the command line.

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 InvalidByteError

type InvalidByteError byte

InvalidByteError values describe errors resulting from an invalid byte in a hex string.

func (InvalidByteError) Error

func (e InvalidByteError) Error() string
