   * Before going into the details of this particular function, let's keep in mind the basics:

   * <ol>
   *   <li>The state of the RateLimiter (storedPermits) is a vertical line in this figure.
   *   <li>When the RateLimiter is not used, this goes right (up to maxPermits)
   *   <li>When the RateLimiter is used, this goes left (down to zero), since if we have

/// warning

/// danger

//// tab | Info

Tabs and `Info`/`Note`/`Warning`/etc. blocks should have the translation of their title added after a vertical bar (`|`).

See sections `### Special blocks` and `### Tab blocks` in the general prompt in `scripts/translate.py`.

## Usando `Union` ou `Optional` { #using-union-or-optional }

Se, por algum motivo, seu código não puder usar `|`, por exemplo, se não for em uma anotação de tipo, mas em algo como `response_model=`, em vez de usar a barra vertical (`|`) você pode usar `Union` do `typing`.

Por exemplo, você poderia declarar que algo pode ser `str` ou `None`:

```python
from typing import Union


def say_hi(name: Union[str, None]):
