Pydantic serileştirmeyi **Rust** tarafında yapacağından, dönüş tipi bildirmediğiniz duruma göre çok daha yüksek **performans** elde edersiniz.

### Async Olmayan Path Operation Fonksiyonları { #non-async-path-operation-functions }

Normal `def` fonksiyonlarını (yani `async` olmadan) da kullanabilir ve aynı şekilde `yield` kullanabilirsiniz.

         * if (tokenizerFactory == null) { final String path = System.getProperty(SuggestConstants.USER_DICT_PATH);
         * final String encoding = System.getProperty(SuggestConstants.USER_DICT_ENCODING); final Map<String, String>
         * args = new HashMap<>(); args.put("mode", "normal"); args.put("discardPunctuation", "false"); if
         * (Strings.isNullOrEmpty(path)) { args.put("userDictionary", path); } if (Strings.isNullOrEmpty(encoding)) {

# Optional Path parameters are not supported...

lo cual sería equivalente a:

```python
from backend.main import app
```

### `fastapi dev` con path { #fastapi-dev-with-path }

También puedes pasar el path del archivo al comando `fastapi dev`, y adivinará el objeto app de FastAPI a usar:

```console
$ fastapi dev main.py
```

Pero tendrías que recordar pasar el path correcto cada vez que llames al comando `fastapi`.

/// tip | Совет

Обратите внимание, что в этом примере мы объявляем path-параметр вместе с параметром `Request`.

Таким образом, path-параметр будет извлечён, валидирован, преобразован к указанному типу и задокументирован в OpenAPI.

Точно так же вы можете объявлять любые другие параметры как обычно и, дополнительно, получать `Request`.

/**

In this case, this `__call__` is what **FastAPI** will use to check for additional parameters and sub-dependencies, and this is what will be called to pass a value to the parameter in your *path operation function* later.

## Parameterize the instance { #parameterize-the-instance }

And now, we can use `__init__` to declare the parameters of the instance that we can use to "parameterize" the dependency:

/// tip | Consejo

Como Pydantic lo serializará en el lado de **Rust**, obtendrás un **rendimiento** mucho mayor que si no declaras un tipo de retorno.

### No async *path operation functions* { #non-async-path-operation-functions }

También puedes usar funciones `def` normales (sin `async`), y usar `yield` de la misma manera.

FastAPI se asegurará de ejecutarlo correctamente para que no bloquee el event loop.
