StackIDs []int

	// StartEv indicates the event type of the corresponding "start"
	// event, if this event is an "end," for a pair of events that
	// represent a time range.
	StartEv Type

	// IsTimedEvent indicates whether this is an event that both
	// appears in the main event stream and is surfaced to the
	// trace reader.
	//
	// Events that are not "timed" are considered "structural"

```

Nesse caso, a função de manipulação de evento `startup` irá inicializar os itens do "banco de dados" (só um `dict`) com alguns valores.

Você pode adicionar mais que uma função de manipulação de evento.

E sua aplicação não irá começar a receber requisições até que todos os manipuladores de eventos de `startup` sejam concluídos.

Diese Funktionen können mit `async def` oder normalem `def` deklariert werden.

### `startup`-Event

Um eine Funktion hinzuzufügen, die vor dem Start der Anwendung ausgeführt werden soll, deklarieren Sie diese mit dem Event `startup`:

```Python hl_lines="8"
{!../../../docs_src/events/tutorial001.py!}
```

	Data []byte
}

// Event represents a single event in the trace.
type Event struct {
	table *evTable
	ctx   schedCtx
	base  baseEvent
}

// Kind returns the kind of event that this is.
func (e Event) Kind() EventKind {
	return go122Type2Kind[e.base.typ]
}

// Time returns the timestamp of the event.
func (e Event) Time() Time {
	return e.base.time
}

		klog.V(4).InfoS("Received Container Created Event", "event", event.String())
	case runtimeapi.ContainerEventType_CONTAINER_STARTED_EVENT:
		e.sendPodLifecycleEvent(&PodLifecycleEvent{ID: types.UID(event.PodSandboxStatus.Metadata.Uid), Type: ContainerStarted, Data: event.ContainerId})
		klog.V(4).InfoS("Received Container Started Event", "event", event.String())
	case runtimeapi.ContainerEventType_CONTAINER_DELETED_EVENT:

```

In this case, the `startup` event handler function will initialize the items "database" (just a `dict`) with some values.

You can add more than one event handler function.

And your application won't start receiving requests until all the `startup` event handlers have completed.

### `shutdown` event

To add a function that should be run when the application is shutting down, declare it with the event `"shutdown"`:
