## docstringによる説明の高度な設定

*path operation関数* のdocstringからOpenAPIに使用する行を制限することができます。

`\f` (「書式送り (Form Feed)」のエスケープ文字) を付与することで、**FastAPI** はOpenAPIに使用される出力をその箇所までに制限します。

ドキュメントには表示されませんが、他のツール (例えばSphinx) では残りの部分を利用できるでしょう。

## Descripción avanzada desde el docstring

Puedes limitar las líneas usadas desde el docstring de una *operación de path* para OpenAPI.

Agregar un `\f` (un carácter de "form feed" escapado) hace que **FastAPI** trunque el output utilizada para OpenAPI en ese punto.

No será mostrado en la documentación, pero otras herramientas (como Sphinx) serán capaces de usar el resto.

## Advanced description from docstring

You can limit the lines used from the docstring of a *path operation function* for OpenAPI.

Adding an `\f` (an escaped "form feed" character) causes **FastAPI** to truncate the output used for OpenAPI at this point.

It won't show up in the documentation, but other tools (such as Sphinx) will be able to use the rest.

   * inputs before escaping them with this escaper.

## Description avancée de docstring

Vous pouvez limiter le texte utilisé de la docstring d'une *fonction de chemin* qui sera affiché sur OpenAPI.

L'ajout d'un `\f` (un caractère d'échappement "form feed") va permettre à **FastAPI** de tronquer la sortie utilisée pour OpenAPI à ce stade.

Il n'apparaîtra pas dans la documentation, mais d'autres outils (tel que Sphinx) pourront utiliser le reste.

## Fortgeschrittene Beschreibung mittels Docstring

Sie können die verwendeten Zeilen aus dem Docstring einer *Pfadoperation-Funktion* einschränken, die für OpenAPI verwendet werden.

Das Hinzufügen eines `\f` (ein maskiertes „Form Feed“-Zeichen) führt dazu, dass **FastAPI** die für OpenAPI verwendete Ausgabe an dieser Stelle abschneidet.

Sie wird nicht in der Dokumentation angezeigt, aber andere Tools (z. B. Sphinx) können den Rest verwenden.
