Functions

func ANDBytes

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 ORBytes

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

func TestBytes(p []byte) bool

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

func XORBytes

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.
