Functions

func CopyDir

func CopyDir(src string, dst string) error

CopyDir copy directory from src to dst.

func CopyFile

func CopyFile(src, dst string) error

CopyFile copy a single file.

func Float64ToStr

func Float64ToStr(val float64) string

Float64ToStr Convert type float64 to string

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 PathExist

func PathExist(path string) bool

PathExist check if the directory or file exists.

func StrToFloat64

func StrToFloat64(val string) (float64, error)

StrToFloat64 convert type string to float64

func NewMurmur128

func NewMurmur128() *Murmur128

func (*Murmur128) EncodeSum128
