Functions ¶

func Blend ¶

func Blend(dst []byte, src []byte) int

Blend copies the one-bits of src to dst, returning the number of bytes written.

func ContainsByte ¶

func ContainsByte(haystack []byte, needle byte) bool

func Copy ¶

func Copy(dst []byte, src []byte) int

Copy copies src to dst, returning the number of bytes written.

func CountPair ¶

func CountPair(b []byte, n int) int

CountPair returns the byte index of the first pair of two equal elements of size n.

If no pairs of equal elements were found, len(b) is returned.

func IndexPair ¶

func IndexPair(b []byte, n int) int

IndexPair returns the byte index of the first pair of two equal elements of size n.

If no pairs of equal elements were found, -1 is returned.

func Mask ¶

func Mask(dst []byte, src []byte) int

Mask set bits of dst to zero and copies the one-bits of src to dst, returning the number of bytes written.
