Types

type Bitset

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

Bitset is an in-memory bitmap that is conceptually similar to []bool, but more memory efficient.

func New

func New(length int64) *Bitset

New returns a new in-memory bitset where you can set, clear and test for individual bits.

func (*Bitset) Clear

func (b *Bitset) Clear(off int64)

Clear sets the bit at position `off` to 0.

func (*Bitset) IsSet

func (b *Bitset) IsSet(off int64) bool

IsSet returns true if the bit at position `off` is 1.

func (*Bitset) Set

func (b *Bitset) Set(off int64)

Set sets the bit at position `off` to 1.
