Types

type Bitmask

type Bitmask struct {
	I map[uint64]uint64
	// contains filtered or unexported fields
}

Bitmask - simple bitmask data structire based on a map

func NewBitMask

func NewBitMask() *Bitmask

NewBitMask - constructor

func (*Bitmask) Empty

func (b *Bitmask) Empty() bool

Empty - return true if bitmask is entirely empty

func (*Bitmask) Has

func (b *Bitmask) Has(val int64) bool

Has - basic get/set methods

func (*Bitmask) Insert

func (b *Bitmask) Insert(val int64)

Insert - basic get/set methods

func (*Bitmask) Len

func (b *Bitmask) Len() uint64

Len - total elements in mask (non performant!)

type PBFMasks

type PBFMasks struct {
	Nodes       *Bitmask
	Ways        *Bitmask
	Relations   *Bitmask
	WayRefs     *Bitmask
	RelNodes    *Bitmask
	RelWays     *Bitmask
	RelRelation *Bitmask
}

PBFMasks - struct to hold common masks .
