    This is useful when we use ConstrainedDecimal to represent Numeric(x,0)
    where a integer (but not int typed) is used. Encoding this as a float
    results in failed round-tripping between encode and parse.
    Our Id type is a prime example of this.

    >>> decimal_encoder(Decimal("1.0"))
    1.0

    >>> decimal_encoder(Decimal("1"))
    1

با **FastAPI** شما تمام ویژگی های **Starlette** را خواهید داشت (زیرا FastAPI یک نسخه و نمونه به تمام معنا از Starlette است):

* عملکرد به طورجدی چشمگیر. <a href="https://github.com/encode/starlette#performance" class="external-link" target="_blank">این یکی از سریعترین فریم ورک های موجود در پایتون است که همتراز با **نود جی اس** و **گو**</a> است.
* پشتیبانی از **WebSocket**.

   * java.nio.file.Files#newBufferedWriter(java.nio.file.Path, Charset,
   * java.nio.file.OpenOption...)}.
   *
   * @param file the file to write to
   * @param charset the charset used to encode the output stream; see {@link StandardCharsets} for
   *     helpful predefined constants
   * @return the buffered writer
   */

因此，我们下一步要做的就是添加代码，为从 API 接收回调的*外部 API*存档。

这部分文档在 `/docs` 下的 Swagger API 文档中显示，并且会告诉外部开发者如何构建*外部 API*。

本例没有实现回调本身（只是一行代码），只有文档部分。

/// tip | "提示"

实际的回调只是 HTTP 请求。

实现回调时，要使用 <a href="https://www.encode.io/httpx/" class="external-link" target="_blank">HTTPX</a> 或 <a href="https://requests.readthedocs.io/" class="external-link" target="_blank">Requests</a>。

## 编写回调文档代码

应用不执行这部分代码，只是用它来*记录 外部 API* 。
