Убедитесь, что вы [обновили версию FastAPI](../deployment/versions.md#upgrading-the-fastapi-versions) как минимум до 0.95.1 перед использованием `Annotated`.

///

## Использовать `Annotated` в типе для параметра `q` { #use-annotated-in-the-type-for-the-q-parameter }

Помните, я уже говорил, что `Annotated` можно использовать для добавления метаданных к параметрам в разделе [Введение в типы Python](../python-types.md#type-hints-with-metadata-annotations)?

Теперь запустите Traefik:

<div class="termy">

```console
$ ./traefik --configFile=traefik.toml

INFO[0000] Configuration loaded from file: /home/user/awesomeapi/traefik.toml
```

</div>

И запустите приложение с опцией `--root-path`:

<div class="termy">

```console
$ fastapi run main.py --forwarded-allow-ips="*" --root-path /api/v1

Тепер запустіть Traefik:

<div class="termy">

```console
$ ./traefik --configFile=traefik.toml

INFO[0000] Configuration loaded from file: /home/user/awesomeapi/traefik.toml
```

</div>

А тепер запустіть ваш застосунок, використовуючи опцію `--root-path`:

<div class="termy">

```console

			if partNeedsHealing(dataErrsPerDisk[diskIndex]) {
				t.Errorf("Disk not expected to be healed, driveIndex: %d", diskIndex)
			}
		}
	}
}

func TestCommonParities(t *testing.T) {
	// This test uses two FileInfo values that represent the same object but
	// have different parities. They occur in equal number of drives, but only
	// one has read quorum. commonParity should pick the parity corresponding to
