Types

type EventCounter

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

EventCounter is used to track events over time, potentially allowing you to limit them per time period

func New

func New(now time.Time, duration time.Duration) EventCounter

New returns a new EventCounter object that resets event counts per duration.

func (*EventCounter) Event

func (a *EventCounter) Event(now time.Time) int64

Event returns the number of events in the time period now. Note, now should be >= the last event threshold. Also, we avoid any loops with compare and swap atomics because we're ok being off a few items as long as we're generally accurate and fast.

func (*EventCounter) Events

func (a *EventCounter) Events(now time.Time, count int64) int64

Events behaves just like Event() but acts on multiple events at once to reduce the number of atomic increment calls
