Functions

func ByteToFloat64

func ByteToFloat64(bytes []byte) float64

func ByteToString

func ByteToString(b []byte) string

ByteToString converts byte slice to a string without memory allocation.

func Float64ToByte

func Float64ToByte(float float64) []byte

func Max

func Max(x, y int) int

func MemHash

func MemHash(buf []byte) uint64

MemHash is the hash function used by go map, it utilizes available hardware instructions(behaves as aeshash if aes instruction is available). NOTE: The hash seed changes for every process. So, this cannot be used as a persistent hash.

func Min

func Min(x, y int) int

func PathExist

func PathExist(path string) bool

func StringToByte

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

StringToByte converts string to a byte slice without memory allocation.
