Constants

const MaxBitmapSize uint64 = 0x01 << 40

MaxBitmapSize is the maximum bitmap size (in bits).

type Bitmap

type Bitmap struct {
    // contains filtered or unexported fields
}

Bitmap represents a bitmap.

func New

func New(size uint64) *Bitmap

New creates a new Bitmap.

func (*Bitmap) GetBit

func (b *Bitmap) GetBit(offset uint64) bool

GetBit returns the value of bit at offset.

func (*Bitmap) SetBit

func (b *Bitmap) SetBit(offset uint64, v bool) bool

SetBit sets bit at offset to value v.

func (*Bitmap) Size

func (b *Bitmap) Size() uint64

Size returns the bitmap size (in bits).
