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

	// 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.
