Starlette (e **FastAPI**) são baseados no <a href="https://anyio.readthedocs.io/en/stable/" class="external-link" target="_blank">AnyIO</a>, o que o torna compatível com ambos o <a href="https://docs.python.org/3/library/asyncio-task.html" class="external-link" target="_blank">asyncio</a> da biblioteca padrão do Python, e o <a href="https://trio.readthedocs.io/en/stable/" class="external-link" target="_blank">Trio</a>.

You can set `schema_extra` with a `dict` containing any additional data you would like to show up in the generated JSON Schema, including `examples`.

////

/// tip

You could use the same technique to extend the JSON Schema and add your own custom extra info.

# Extra Data Types { #extra-data-types }

Up to now, you have been using common data types, like:

* `int`
* `float`
* `str`
* `bool`

But you can also use more complex data types.

And you will still have the same features as seen up to now:

* Great editor support.
* Data conversion from incoming requests.
* Data conversion for response data.
* Data validation.
* Automatic annotation and documentation.

So, we get a Pydantic model from the data in another Pydantic model.

#### Unpacking a `dict` and extra keywords { #unpacking-a-dict-and-extra-keywords }

And then adding the extra keyword argument `hashed_password=hashed_password`, like in:

```Python
UserInDB(**user_in.dict(), hashed_password=hashed_password)
```

...ends up being like:

    * `Path()`
    * `Query()`
    * `Header()`
    * `Cookie()`

Starlette (y **FastAPI**) están basados en <a href="https://anyio.readthedocs.io/en/stable/" class="external-link" target="_blank">AnyIO</a>, lo que lo hace compatible tanto con la librería estándar de Python <a href="https://docs.python.org/3/library/asyncio-task.html" class="external-link" target="_blank">asyncio</a> como con <a href="https://trio.readthedocs.io/en/stable/" class="external-link" target="_blank">Trio</a>.

### Sous-dépendances

Vous pouvez avoir de multiples dépendances et sous-dépendances dépendant les unes des autres (en tant que paramètres de la définition de la *fonction de chemin*), certaines créées avec `async def` et d'autres avec `def`. Cela fonctionnerait aussi, et celles définies avec un simple `def` seraient exécutées sur un thread externe (venant de la threadpool) plutôt que d'être "attendues".

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

would be valid to use as a **FastAPI** dependency.

In fact, FastAPI uses those two decorators internally.
