# Cuerpo - Modelos Anidados

Con **FastAPI**, puedes definir, validar, documentar y usar modelos anidados de manera arbitraria (gracias a Pydantic).

## Campos de lista

Puedes definir un atributo como un subtipo. Por ejemplo, una `list` en Python:

{* ../../docs_src/body_nested_models/tutorial001_py310.py hl[12] *}

Esto hará que `tags` sea una lista, aunque no declare el tipo de los elementos de la lista.

## Campos de lista con parámetro de tipo

     * {@code rootDirectory}, especially if a subtree of the project is being
     * built, either because Maven has been launched in a subdirectory or using
     * a {@code -f} option.

Com o **FastAPI**, você pode definir, validar, documentar e usar modelos profundamente aninhados de forma arbitrária (graças ao Pydantic).

## Campos do tipo Lista

Você pode definir um atributo como um subtipo. Por exemplo, uma `list` do Python:

{* ../../docs_src/body_nested_models/tutorial001.py hl[14] *}

Isso fará com que tags seja uma lista de itens mesmo sem declarar o tipo dos elementos desta lista.

 *   <li>All events for a given listener dispatch on the provided executor.
 *   <li>It is easy for the user to ensure that listeners are never invoked while holding locks.
 * </ul>
 *
 * The last point is subtle. Often the observable object will be managing its own internal state
 * using a lock, however it is dangerous to dispatch listeners while holding a lock because they

Using `rsa1024min=0` restores the Go 1.23 behavior.

Go 1.24 introduced a mechanism for enabling platform specific Data Independent
Timing (DIT) modes in the [`crypto/subtle`](/pkg/crypto/subtle) package. This
mode can be enabled for an entire program with the `dataindependenttiming` setting.
For Go 1.24 it defaults to `dataindependenttiming=0`. There is no change in default
