Variables ¶

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
