Types ¶

type Heartbeat ¶ added in v0.0.23

type Heartbeat struct {
	Clock clockwork.Clock
	// contains filtered or unexported fields
}

Heartbeat will call the provided HeartbeatFunc on the supplied period for each enqueued element.

func NewHeartbeat ¶ added in v0.0.23

func NewHeartbeat(period time.Duration, fn HeartbeatFunc) *Heartbeat

func (*Heartbeat) Dequeue ¶ added in v0.0.23

func (h *Heartbeat) Dequeue(id string)

Dequeue removes the heartbeat associated with the id from the list. This is roughly a log(n) runtime. There is _some_ scanning involved, but it's only in the event that two heartbeats are scheduled at the same time.

func (*Heartbeat) Enqueue ¶ added in v0.0.23

func (h *Heartbeat) Enqueue(ctx context.Context, id string)

Enqueue adds the provided id to the list of elements to process. If runNow is true, then the element is enqueued using the current timestamp rather than one in the future. This operation should be close to log(n) runtime.

func (*Heartbeat) Poll ¶ added in v0.0.23

func (h *Heartbeat) Poll(ctx context.Context)

Poll reads from the head of the queue until we reach an entry with a greater timestamp.

func (*Heartbeat) Start ¶ added in v0.0.23

func (h *Heartbeat) Start(ctx context.Context)

Start forks a go routine until the provided context is cancelled. Every 200 ms, it attempts to poll the underlying queue for entries that need to be processed.

type HeartbeatFunc ¶ added in v0.0.23

type HeartbeatFunc func(ctx context.Context, id string)
