Functions

func DirSize

func DirSize(dirPath string) (int64, error)

DirSize get directory size

func GetTestKey

func GetTestKey(i int) []byte

GetTestKey get formatted key, for test only

func MemHash

func MemHash(data []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 MemHashString

func MemHashString(str string) uint64

MemHashString 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 RandomValue

func RandomValue(n int) []byte

RandomValue generate random value, for test only
