Functions

func BytesToString

func BytesToString(b []byte) string

BytesToString converts byte slice to a string without memory allocation.

Note it may break if the implementation of string or slice header changes in the future go versions.

func CeilToPowerOfTwo

func CeilToPowerOfTwo(n int) int

CeilToPowerOfTwo returns the least power of two integer value greater than or equal to n.

func FloorToPowerOfTwo

func FloorToPowerOfTwo(n int) int

FloorToPowerOfTwo returns the greatest power of two integer value less than or equal to n.

func IsPowerOfTwo

func IsPowerOfTwo(n int) bool

IsPowerOfTwo reports whether given integer is a power of two.

func StringToBytes

func StringToBytes(s string) (b []byte)
