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 Has0xPrefix

func Has0xPrefix(str string) bool

has0xPrefix validates str begins with '0x' or '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 IsHex

func IsHex(str string) bool

isHex validates whether each byte is valid hexadecimal string.

func IsHexCharacter

func IsHexCharacter(c byte) bool

isHexCharacter returns bool of c being a valid hexadecimal.

func LeftPadBytes

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

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

func ParseHexOrString

func ParseHexOrString(str string) ([]byte, error)

ParseHexOrString tries to hexdecode b, but if the prefix is missing, it instead just returns the raw bytes

func RightPadBytes

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

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

func TrimLeftZeroes

func TrimLeftZeroes(s []byte) []byte

TrimLeftZeroes returns a subslice of s without leading zeroes

func TrimRightZeroes

func TrimRightZeroes(s []byte) []byte

TrimRightZeroes returns a subslice of s without trailing zeroes
