### Modelo de Entrada en la Documentación { #input-model-in-docs }

Puedes confirmar eso en la documentación, el campo `description` no tiene un **asterisco rojo**, no está marcado como requerido:

<div class="screenshot">
<img src="/img/tutorial/separate-openapi-schemas/image01.png">
</div>

### Modelo para Salida { #model-for-output }

Pero si usas el mismo modelo como salida, como aquí:

### Modelo de Entrada na Documentação { #input-model-in-docs }

Você pode confirmar que na documentação, o campo `description` não tem um **asterisco vermelho**, não é marcado como obrigatório:

<div class="screenshot">
<img src="/img/tutorial/separate-openapi-schemas/image01.png">
</div>

### Modelo para Saída { #model-for-output }

Mas se você usar o mesmo modelo como saída, como aqui:

/**
 *<strong>Warning:</strong> This is an internal utility class that is only public for technical reasons, it is not part
 * of the public API. In particular, this class can be changed or deleted without prior notice. Use
 * {@link org.apache.maven.project.MavenProjectHelper#attachArtifact} instead.
 */
@Deprecated
public class AttachedArtifact extends DefaultArtifact {

    private final Artifact parent;

Все блоки кода можно копировать и использовать напрямую (это действительно протестированные файлы Python).

Чтобы запустить любой из примеров, скопируйте код в файл `main.py` и запустите `fastapi dev` с:

<div class="termy">

```console
$ <font color="#4E9A06">fastapi</font> dev <u style="text-decoration-style:solid">main.py</u>

///

/// note | 技术细节

任何一个可以与以下内容一起使用的函数：

* <a href="https://docs.python.org/3/library/contextlib.html#contextlib.contextmanager" class="external-link" target="_blank">`@contextlib.contextmanager`</a> 或者
* <a href="https://docs.python.org/3/library/contextlib.html#contextlib.asynccontextmanager" class="external-link" target="_blank">`@contextlib.asynccontextmanager`</a>

都可以作为 **FastAPI** 的依赖项。

实际上，FastAPI内部就使用了这两个装饰器。

（和 **FastAPI**） 是基于 <a href="https://anyio.readthedocs.io/en/stable/" class="external-link" target="_blank">AnyIO</a> 实现的，这使得它们可以兼容 Python 的标准库 <a href="https://docs.python.org/3/library/asyncio-task.html" class="external-link" target="_blank">asyncio</a> 和 <a href="https://trio.readthedocs.io/en/stable/" class="external-link" target="_blank">Trio</a>。

特别是，你可以直接使用 <a href="https://anyio.readthedocs.io/en/stable/" class="external-link" target="_blank">AnyIO</a> 来处理高级的并发用例，这些用例需要在自己的代码中使用更高级的模式。...
