A variável `oauth2_scheme` é um instância de `OAuth2PasswordBearer`, mas também é um "callable".

Pode ser chamada de:

```Python
oauth2_scheme(some, parameters)
```

Então, pode ser usado com `Depends`.

## Use-o

Agora você pode passar aquele `oauth2_scheme` em uma dependência com `Depends`.

   * <p>To ensure that the created instance obeys its contract, the parameters should satisfy the
   * following constraints. This is the callers responsibility and is not enforced here.

   * <ul>
   *   <li>If {@code count} is 0, {@code mean} may have any finite value (its only usage will be to
   *       get multiplied by 0 to calculate the sum), and the other parameters may have any values
   *       (they will not be used).

This behavior is consistent across all keys; each key self-documents itself with valid examples.

The following sub-systems are dynamic i.e., configuration parameters for each sub-systems can be changed while the server is running without any restarts.
