/// info | Información

La clave `model` no es parte de OpenAPI.

**FastAPI** tomará el modelo de Pydantic de allí, generará el JSON Schema y lo colocará en el lugar correcto.

El lugar correcto es:

* En la clave `content`, que tiene como valor otro objeto JSON (`dict`) que contiene:

    void addEventMonitor(EventMonitor monitor);

    void dispatchStart(String event, String target);

    void dispatchEnd(String event, String target);

    void dispatchError(String event, String target, Throwable cause);

    'full_name': None,
}
```

#### Desempaquetando un `dict` { #unpacking-a-dict }

Si tomamos un `dict` como `user_dict` y lo pasamos a una función (o clase) con `**user_dict`, Python lo "desempaquetará". Pasará las claves y valores del `user_dict` directamente como argumentos clave-valor.

Así que, continuando con el `user_dict` anterior, escribir:

```Python
UserInDB(**user_dict)
```

sería equivalente a algo como:

 * }
 * public void testFooLeak() {
 *   GcFinalization.awaitClear(fooWeakRef());
 * }
 * }
 *
 * <p>This class cannot currently be used to test soft references, since this class does not try to
 * create the memory pressure required to cause soft references to be cleared.
 *
 * <p>This class only provides testing utilities. It is not designed for direct use in production or
 * for benchmarking.
 *

    assertThat(future.set(1)).isTrue();
    assertSuccessful(future, 1);
  }

  public void testFailed() throws Exception {
    Exception cause = new Exception();
    assertThat(future.setException(cause)).isTrue();
    assertFailed(future, cause);
  }

  public void testCanceled() throws Exception {
    assertThat(future.cancel(false /* mayInterruptIfRunning */)).isTrue();
    assertCancelled(future, false);

 *       running on it. This class, by contrast, does not expose an {@code Executor} API.)
 * </ul>
 *
 * <p>If you don't need the features of this class, you may prefer {@code newSequentialExecutor} for
 * its simplicity and ability to accommodate interruption.
