Types

type Set

type Set []byte

Set manages an arbitrary set of bits.

func (*Set) Clear

func (b *Set) Clear(i int)

func (*Set) Is

func (b *Set) Is(i int) bool

func (*Set) Set

func (b *Set) Set(i int)

type Set128

type Set128 [8 * 2]byte

Set128 manages a set of 128 bits.

A panic occurs if you try to Set, Clear or Check outside range 0-127.

func (*Set128) Clear

func (x *Set128) Clear(pos byte)

func (*Set128) Is

func (x *Set128) Is(pos byte) bool

func (*Set128) Set

func (x *Set128) Set(pos byte)

type Set256

type Set256 [8 * 4]byte

Set256 manages a set of 256 bits.

func (*Set256) Clear

func (x *Set256) Clear(pos byte)

func (*Set256) Is

func (x *Set256) Is(pos byte) bool

func (*Set256) Set

func (x *Set256) Set(pos byte)

type Set64

type Set64 [8 * 1]byte

Set64 manages a set of 64 bits.

A panic occurs if you try to Set, Clear or Check outside range 0-63.

func (*Set64) Clear

func (x *Set64) Clear(pos byte)

func (*Set64) Is

func (x *Set64) Is(pos byte) bool

func (*Set64) Set

func (x *Set64) Set(pos byte)
