This is particularly useful when automatically generating clients or
                SDKs for your API.

                Read more about it in the
                [FastAPI docs about how to Generate Clients](https://fastapi.tiangolo.com/advanced/generate-clients/#custom-generate-unique-id-function).
                """
            ),
        ] = Default(generate_unique_id),

Der Hauptanwendungsfall hierfür besteht wahrscheinlich darin, dass Sie das mal tun möchten, wenn Sie bereits über einige automatisch generierte Client-Codes/SDKs verfügen und im Moment nicht alle automatisch generierten Client-Codes/SDKs aktualisieren möchten, möglicherweise später, aber nicht jetzt.

In diesem Fall können Sie diese Funktion in **FastAPI** mit dem Parameter `separate_input_output_schemas=False` deaktivieren.
