Functions

func Bytes

func Bytes(hex string) ([]byte, error)

Bytes parses the hex-string of odd length into bytes.

func HexString

func HexString(octets []byte) string

HexString produces a hex-string from bytes. Like a DEADBEEF, without prepending the 0x.

func MustBytes

func MustBytes(hex string) []byte

MustBytes is an alias for Bytes, except that it will panic if there is any parse error.

func SplitStringBySize

func SplitStringBySize(str string, maxSize int) []string

SplitStringBySize Split string to parts by size (https://play.golang.org/p/uUKx0hsm_O)
