bitutil.go compress.go

func ANDBytes Uses

❖
func ANDBytes(dst, a, b []byte) int

ANDBytes ands the bytes in a and b. The destination is assumed to have enough space. Returns the number of bytes and'd.

func CompressBytes Uses

❖
func CompressBytes(data []byte) []byte

CompressBytes compresses the input byte slice according to the sparse bitset representation algorithm. If the result is bigger than the original input, no compression is done.

func DecompressBytes Uses

❖
func DecompressBytes(data []byte, target int) ([]byte, error)

DecompressBytes decompresses data with a known target size. If the input data matches the size of the target, it means no compression was done in the first place.

func ORBytes Uses

❖
func ORBytes(dst, a, b []byte) int

ORBytes ors the bytes in a and b. The destination is assumed to have enough space. Returns the number of bytes or'd.

func TestBytes Uses

❖
func TestBytes(p []byte) bool

TestBytes tests whether any bit is set in the input byte slice.

func XORBytes Uses

❖
func XORBytes(dst, a, b []byte) int

XORBytes xors the bytes in a and b. The destination is assumed to have enough space. Returns the number of bytes xor'd.
