## Lee primero el Tutorial { #read-the-tutorial-first }

Aún podrías usar la mayoría de las funcionalidades en **FastAPI** con el conocimiento del [Tutorial - Guía del usuario](../tutorial/index.md){.internal-link target=_blank} principal.

        String result = circuitBreaker.executeWithCircuitBreaker(() -> "success 0");

И вполне возможно, что для вашего случая использования решение находится в одном из них.

## Сначала прочитайте Учебник - Руководство пользователя { #read-the-tutorial-first }

Вы все еще можете использовать большинство функций **FastAPI** со знаниями из [Учебник - Руководство пользователя](../tutorial/index.md){.internal-link target=_blank}.
