Functions ¶

func Bytes2Hex ¶

func Bytes2Hex(d []byte) string

Bytes2Hex returns the hexadecimal encoding of d.

func CopyBytes ¶

func CopyBytes(b []byte) (copiedBytes []byte)

CopyBytes returns an exact copy of the provided bytes.

func FromHex ¶

func FromHex(s string) []byte

FromHex returns the bytes represented by the hexadecimal string s. s may be prefixed with "0x".

func Hex2Bytes ¶

func Hex2Bytes(str string) []byte

Hex2Bytes returns the bytes represented by the hexadecimal string str.

func Hex2BytesFixed ¶

func Hex2BytesFixed(str string, flen int) []byte

Hex2BytesFixed returns bytes of a specified fixed length flen.

func LeftPadBytes ¶

func LeftPadBytes(slice []byte, l int) []byte

LeftPadBytes zero-pads slice to the left up to length l.

func RightPadBytes ¶

func RightPadBytes(slice []byte, l int) []byte

RightPadBytes zero-pads slice to the right up to length l.

func ToHex deprecated

func ToHex(b []byte) string

ToHex returns the hex representation of b, prefixed with '0x'. For empty slices, the return value is "0x0".

Deprecated: use hexutil.Encode instead.

func ToHexArray ¶ added in v1.0.0

func ToHexArray(b [][]byte) []string

ToHexArray creates a array of hex-string based on []byte
