Functions

func Clone

func Clone(src, dst interface{}) error

deep clone object from a to b

func Compress

func Compress(b []byte) []byte

func Expand

func Expand(b []byte) []byte

func PaddedAppend

func PaddedAppend(size uint, src []byte) []byte

PaddedAppend appends the src byte slice to dst, returning the new slice. If the length of the source is smaller than the passed size, leading zero bytes are appended to the dst slice before appending src.

func PrettyPrintJson

func PrettyPrintJson(b []byte) []byte

func RandString

func RandString(ulen uint8) string

func Rcopy

func Rcopy(dst []byte, src []byte) int

func String

func String(b []byte) string

func Uint64ToBytes

func Uint64ToBytes(i uint64) []byte
