Assim como quando declaramos parâmetros de consulta, quando um atributo do modelo possui um valor padrão, ele se torna opcional. Caso contrário, se torna obrigatório. Use `None` para torná-lo opcional.

Por exemplo, o modelo acima declara um JSON "`object`" (ou `dict` no Python) como esse:

```JSON
{
    "name": "Foo",

 * methods of the delegate. For example, overriding {@link #put} alone <i>will not</i> change the
 * behavior of {@link #putAll}, which can lead to unexpected behavior. In this case, you should
 * override {@code putAll} as well, either providing your own implementation, or delegating to the
 * provided {@code standardPutAll} method.
 *

     * StackOverflowError: We can't reliably call setException(error).
     *
     * - Any kind of Error from a listener. Even if we could distinguish that case (by exposing some
     * extra state from AbstractFuture), our options are limited: A call to setException() would be
     * a no-op. We could log, but if that's what we really want, we should modify

    For example, in an HTTP Bearer token scheme, the client will send a header
    like:

    ```
    Authorization: Bearer deadbeef12346
    ```

    In this case:

    * `scheme` will have the value `"Bearer"`
    * `credentials` will have the value `"deadbeef12346"`
    """

    scheme: Annotated[
        str,
        Doc(
            """

}
```

Input for the key is the object name specified in `PutObject()`, returns a unique index. This index is one of the erasure sets where the object will reside. This function is a consistent hash for a given object name i.e for a given object name the index returned is always the same.

	// current cluster does not have the object yet. This is in a site/bucket replication scenario.
	MinIOTaggingProxied = "X-Minio-Tagging-Proxied"
	// Header indicates the actual replicated object size
	// In case of SSEC objects getting replicated (multipart) actual size would be needed at target
	MinIOReplicationActualObjectSize = "X-Minio-Replication-Actual-Object-Size"

	// predicted date/time of transition
