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

Limiter limits the number of added items.

It is safe using the Limiter from concurrent goroutines.

func NewLimiter(maxItems int, refreshInterval time.Duration) *Limiter

NewLimiter creates new Limiter, which can hold up to maxItems unique items during the given refreshInterval.

func (l *Limiter) Add(h uint64) bool

Add adds h to the limiter.

It is safe calling Add from concurrent goroutines.

True is returned if h is added or already exists in l. False is returned if h cannot be added to l, since it already has maxItems unique items.

func (l *Limiter) CurrentItems() int

CurrentItems return the current number of items registered in l.

func (l *Limiter) MaxItems() int

MaxItems returns the maxItems passed to NewLimiter.
