Add an event handler function for startup or shutdown.

        This method is kept for backward compatibility after Starlette removed
        support for on_startup/on_shutdown handlers.

        Ref: https://github.com/Kludex/starlette/pull/3117
        """
        assert event_type in ("startup", "shutdown")
        if event_type == "startup":
            self.on_startup.append(func)
        else:

}

// Prints the formatted startup message.
func printStartupMessage(apiEndpoints []string, err error) {
	banner := strings.Repeat("-", len(MinioBannerName))
	if globalIsDistErasure {
		logger.Startup(color.Bold(banner))
	}
	logger.Startup(color.Bold(MinioBannerName))
	if err != nil {
		if globalConsoleSys != nil {

    def main() -> dict[str, str]:
        return {"message": "Hello World"}

    @app.on_event("startup")
    def app_startup() -> None:
        state.app_startup = True

    @app.on_event("shutdown")
    def app_shutdown() -> None:
        state.app_shutdown = True

    router = APIRouter()

    @router.on_event("startup")
    def router_startup() -> None:
        state.router_startup = True

### `startup`-Event { #startup-event }

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

{* ../../docs_src/events/tutorial001_py310.py hl[8] *}

In diesem Fall initialisiert die Eventhandler-Funktion `startup` die „Datenbank“ der Items (nur ein `dict`) mit einigen Werten.

     <span style="background-color:#007166"><font color="#D3D7CF"> INFO </font></span>  Waiting for application startup.
     <span style="background-color:#007166"><font color="#D3D7CF"> INFO </font></span>  Waiting for application startup.
     <span style="background-color:#007166"><font color="#D3D7CF"> INFO </font></span>  Waiting for application startup.

///

Есть альтернативный способ определить логику, которую нужно выполнить во время startup и во время shutdown.

Вы можете определить обработчики событий (функции), которые нужно выполнить до старта приложения или при его завершении.

Эти функции можно объявить с `async def` или обычным `def`.

### Событие `startup` { #startup-event }

     <span style="background-color:#007166"><font color="#D3D7CF"> INFO </font></span>  Waiting for application startup.
     <span style="background-color:#007166"><font color="#D3D7CF"> INFO </font></span>  Waiting for application startup.
     <span style="background-color:#007166"><font color="#D3D7CF"> INFO </font></span>  Waiting for application startup.

     <span style="background-color:#007166"><font color="#D3D7CF"> INFO </font></span>  Waiting for application startup.
     <span style="background-color:#007166"><font color="#D3D7CF"> INFO </font></span>  Waiting for application startup.
     <span style="background-color:#007166"><font color="#D3D7CF"> INFO </font></span>  Waiting for application startup.

     <span style="background-color:#007166"><font color="#D3D7CF"> INFO </font></span>  Waiting for application startup.
     <span style="background-color:#007166"><font color="#D3D7CF"> INFO </font></span>  Waiting for application startup.
     <span style="background-color:#007166"><font color="#D3D7CF"> INFO </font></span>  Waiting for application startup.

These functions can be declared with `async def` or normal `def`.

### `startup` event { #startup-event }

To add a function that should be run before the application starts, declare it with the event `"startup"`:

{* ../../docs_src/events/tutorial001_py310.py hl[8] *}

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