**FastAPI** はすべてPydanticをベースにしています。

すべてのことは[チュートリアル - ユーザーガイド](tutorial/index.md){.internal-link target=_blank}で実際に見ることができます。

## **FastAPI**での型ヒント

**FastAPI** はこれらの型ヒントを利用していくつかのことを行います。

    maybePropagateCancellationTo(localInputFuture);
    this.inputFuture = null;
    this.exceptionType = null;
    this.fallback = null;
  }

  /**
   * An {@link AbstractCatchingFuture} that delegates to an {@link AsyncFunction} and {@link
   * #setFuture(ListenableFuture)}.
   */
  private static final class AsyncCatchingFuture<V extends @Nullable Object, X extends Throwable>
      extends AbstractCatchingFuture<

Zum Beispiel bietet **FastAPI** selbst eine alternative API-Dokumentation (verwendet ReDoc), welche Sie unter <a href="http://127.0.0.1:8000/redoc" class="external-link" target="_blank">http://127.0.0.1:8000/redoc</a> einsehen können:

  /**
   * Indicates whether another object is equal to this predicate.
   *
   * <p>Most implementations will have no reason to override the behavior of {@link Object#equals}.
   * However, an implementation may also choose to return {@code true} whenever {@code object} is a
   * {@link Predicate} that it considers <i>interchangeable</i> with this one. "Interchangeable"

## 경고

만약 무거운 백그라운드 작업을 수행해야하고 동일한 프로세스에서 실행할 필요가 없는 경우 (예: 메모리, 변수 등을 공유할 필요가 없음) <a href="https://docs.celeryq.dev" class="external-link" target="_blank">`Celery`</a>와 같은 큰 도구를 사용하면 도움이 될 수 있습니다.
