* Großartige Editor-Unterstützung.
* Datenkonvertierung bei eingehenden Requests.
* Datenkonvertierung für Response-Daten.
* Datenvalidierung.
* Automatische Annotation und Dokumentation.

## Andere Datentypen

Hier sind einige der zusätzlichen Datentypen, die Sie verwenden können:

* `UUID`:
    * Ein standardmäßiger „universell eindeutiger Bezeichner“ („Universally Unique Identifier“), der in vielen Datenbanken und Systemen als ID üblich ist.
