Types

type BasicOps

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

BasicOps handles basic bitmap operations

func NewBasicOps

func NewBasicOps(cache *sync.Map, version *sync.Map) *BasicOps

NewBasicOps creates a new BasicOps instance

func (*BasicOps) CreateBitmap

func (b *BasicOps) CreateBitmap(key string, size int) error

CreateBitmap creates a new bitmap of given size

func (*BasicOps) GetBit

func (b *BasicOps) GetBit(key string, offset int64) (int, error)

GetBit returns the bit value at offset

func (*BasicOps) GetBitmap

func (b *BasicOps) GetBitmap(key string) []byte

GetBitmap returns the underlying byte slice for a key

func (*BasicOps) SetBit

func (b *BasicOps) SetBit(key string, offset int64, value int) (int, error)

SetBit sets the bit at offset to value and returns the old value
