Da es sich stattdessen um ein „asynchrones“ System handelt, kann die Aufgabe nach Abschluss ein wenig (einige Mikrosekunden) in der Schlange warten, bis der Computer / das Programm seine anderen Dinge erledigt hat und zurückkommt, um die Ergebnisse entgegenzunehmen und mit ihnen weiterzuarbeiten.

## Zusätzliche Validierung { #additional-validation }

Wir werden sicherstellen, dass, obwohl `q` optional ist, wann immer es bereitgestellt wird, **seine Länge 50 Zeichen nicht überschreitet**.

### `Query` und `Annotated` importieren { #import-query-and-annotated }

Um dies zu erreichen, importieren Sie zuerst:

* `Query` von `fastapi`
* `Annotated` von `typing`

Wenn wir `-> HeroPublic` deklariert hätten, würden Ihr Editor und Linter (zu Recht) reklamieren, dass Sie ein `Hero` anstelle eines `HeroPublic` zurückgeben.

Durch die Deklaration in `response_model` sagen wir **FastAPI**, dass es seine Aufgabe erledigen soll, ohne die Typannotationen und die Hilfe von Ihrem Editor und anderen Tools zu beeinträchtigen.

 * support {@link Iterator#remove}. If the table is modified after an iterator is created, the
 * iterator remains valid.

 * <p>This class requires less memory than the {@link HashBasedTable} and {@link TreeBasedTable}
 * implementations, except when the table is sparse.

 * <p>Null row keys or column keys are not permitted.

 * if you are writing a application that needs to aggressively release unused resources you may do
 * so.

 * Shutdown the dispatcher's executor service with [shutdown()][ExecutorService.shutdown]. This will
