The whole **FastAPI** framework is based to satisfy that. Autocompletion works everywhere.

You will rarely need to come back to the docs.

Here's how your editor might help you:

* in [Visual Studio Code](https://code.visualstudio.com/):

![editor support](https://fastapi.tiangolo.com/img/vscode-completion.png)

   * ListenableFuture<Integer> faultTolerantFuture =
   *     fetchCounters().catchingAsync(
   *         FetchException.class, x -> immediateFuture(0), directExecutor());
   * }
   *
   * <p>The fallback can also choose to propagate the original exception when desired:
   *
   * {@snippet :
   * // Falling back to a zero counter only in case the exception was a
   * // TimeoutException.

var errMalformedEncoding = errors.New("malformed chunked encoding")

// chunk is considered too big if its bigger than > 16MiB.
var errChunkTooBig = errors.New("chunk too big: choose chunk size <= 16MiB")

// newSignV4ChunkedReader returns a new s3ChunkedReader that translates the data read from r
// out of HTTP "chunked" format before returning it.

                new String[] { SuggestConstants.DEFAULT_ROLE }, null, SuggestItem.Kind.DOCUMENT);

        // The timeout value should come from settings, not hardcoded
        SuggestWriterResult result =
                writer.write(runner.client(), suggester.settings(), suggester.getIndex(), new SuggestItem[] { item }, true);

        assertNotNull(result);

 * degrades more gracefully for worst-case input.
 *
 * <p>The implementation does not necessarily use a <i>stable</i> sorting algorithm; when multiple
 * equivalent elements are added to it, it is undefined which will come first in the output.

En validant les données avec Pydantic, nous pouvons nous assurer que nous avons, par exemple, exactement une `list` de `str` pour les scopes et un `str` pour le `username`.

Au lieu, par exemple, d’un `dict`, ou autre chose, ce qui pourrait casser l’application plus tard et constituer un risque de sécurité.

Nous vérifions également que nous avons un utilisateur avec ce nom d’utilisateur, et sinon, nous levons la même exception que précédemment.
