The query parameter `q` is of type `str | None`, that means that it's of type `str` but could also be `None`, and indeed, the default value is `None`, so FastAPI will know it's not required.

/// note

FastAPI will know that the value of `q` is not required because of the default value `= None`.

Having `str | None` will allow your editor to give you better support and detect errors.

#### Etcd

MinIO supports storing encrypted IAM assets in etcd, if KMS is configured. Please refer to how to encrypt your config and IAM credentials [here](https://github.com/minio/minio/blob/master/docs/kms/IAM.md).

     * mirror, its URL and ID will be updated to match the values from the mirror specification. Repositories without a
     * matching mirror will pass through unchanged. Note: This method must be called before
     * {@link #injectAuthentication(List, List)} or the repositories will end up with the wrong credentials.

/// note | Hinweis

Der Befehl `uvicorn main:app` bezieht sich auf:

* `main`: die Datei `main.py` (das sogenannte Python-„Modul“).
* `app`: das Objekt, welches in der Datei `main.py` mit der Zeile `app = FastAPI()` erzeugt wurde.

For example, to declare a `title` metadata value for the path parameter `item_id` you can type:

{* ../../docs_src/path_params_numeric_validations/tutorial001_an_py310.py hl[10] *}

/// note

A path parameter is always required as it has to be part of the path. Even if you declared it with `None` or set a default value, it would not affect anything, it would still be always required.

///

Por exemplo para declarar um valor de metadado `title` para o parâmetro de rota `item_id` você pode digitar:

{* ../../docs_src/path_params_numeric_validations/tutorial001_py310.py hl[8] *}

/// note | Nota

Um parâmetro de rota é sempre obrigatório, como se fizesse parte da rota.

Então, você deve declará-lo com `...` para marcá-lo como obrigatório.
