Functions

func CopyBytes

func CopyBytes(b []byte) []byte

CopyBytes returns a copy of the provided byte slice. If nil is provided, nil will be returned.

func IsSorted2DBytes

func IsSorted2DBytes(arr [][]byte) bool

IsSorted2DBytes returns true iff [arr] is sorted

func IsSortedAndUnique

func IsSortedAndUnique(data sort.Interface) bool

IsSortedAndUnique returns true if the elements in the data are unique and sorted.

func IsSortedAndUniqueUint32

func IsSortedAndUniqueUint32(arr []uint32) bool

IsSortedAndUniqueUint32 returns true if the array of uint32s are sorted and unique

func IsSortedAndUniqueUint64

func IsSortedAndUniqueUint64(u64 []uint64) bool

IsSortedAndUniqueUint64 returns true if the array of uint64s are sorted and unique

func RandomBytes

func RandomBytes(n int) []byte

RandomBytes returns a slice of n random bytes Intended for use in testing

func Sort2DBytes

func Sort2DBytes(arr [][]byte)

Sort2DBytes sorts a 2D byte array Each byte array is not sorted internally; the byte arrays are sorted relative to another.

func SortUint32

func SortUint32(u32 []uint32)

SortUint32 sorts an uint32 array

func SortUint64

func SortUint64(u64 []uint64)

SortUint64 sorts an uint64 array
