   * There is no need for a blocking lock; when the lock is not
   * available, threads try other slots (or the base).  During these
   * retries, there is increased contention and reduced locality,

Le schéma **OpenAPI** est ce qui alimente les deux systèmes de documentation interactive.

Et il existe des dizaines d'alternatives, toutes basées sur **OpenAPI**. Vous pourriez facilement ajouter n'importe laquelle de ces alternatives à votre application **FastAPI**.

Vous pourriez aussi l'utiliser pour générer du code automatiquement, pour les clients qui communiquent avec votre API. Comme par exemple, des applications frontend, mobiles ou IOT.

これがその歴史のほんの一部です。

## 代替手段

数年前から、私は複雑な要件を持つAPI (機械学習、分散システム、非同期ジョブ、NoSQLデータベースなど) を作成しており、いくつかの開発者チームを率いています。

その一環で、多くの方法を調査し、テストし、利用する必要がありました。

**FastAPI** の歴史は、その前身の歴史が大部分を占めています。

[代替ツールから受けたインスピレーションと比較](alternatives.md){.internal-link target=_blank}のセクションでこう述べています:

**FastAPI**は、代替ツールのこれまでの働きがなければ存在しなかったでしょう。

以前に作られた多くのツールが、作成における刺激として役立ってきました。

 *   <li>It doesn't offer much monitoring.
 *   <li>It doesn't propagate exceptions, so apps don't have a way to react to them.
 *   <li>It doesn't interoperate well with RxJava, coroutines, and other more commonly used
 *       alternatives.
 *   <li>It imposes requirements on the lifecycle of its subscribers. For example, if an event
 *       occurs between when one subscriber is removed and the next subscriber is added, the event
 *       is dropped.

    * Objetos `datetime`.
    * Objetos `UUID`.
    * Modelos de base de datos.
    * ...y muchos más.
* Documentación interactiva automática de la API, incluyendo 2 interfaces de usuario alternativas:
    * Swagger UI.
    * ReDoc.

Volviendo al ejemplo de código anterior, **FastAPI**:

* Validará que haya un `item_id` en el path para requests `GET` y `PUT`.

Voltando ao código do exemplo anterior, **FastAPI** irá:

* Validar que existe um `item_id` na rota para requisições `GET` e `PUT`.

 * which will still appear when iterating over the table's contents in a foreach loop or a call to a

 * <p>The allowed row and column keys must be supplied when the table is created. The table always

   * <p>This is designed for generating persistent fingerprints of strings. It isn't
   * cryptographically secure, but it produces a high-quality hash with fewer collisions than some
   * alternatives we've used in the past.

   * <p>FarmHash fingerprints are encoded by {@link HashCode#asBytes} in little-endian order. This
   * means {@link HashCode#asLong} is guaranteed to return the same value that
