 * this structure is never mutated, it provides a thread-safe view of the backing map.
 *
 * <p>The {@link MapIteratorCache} assumes ownership of the backing map, and cannot guarantee
 * correctness in the face of external mutations to the backing map. As such, it is <b>strongly</b>
 * recommended that the caller does not persist a reference to the backing map (unless the backing
 * map is immutable).

   * grab a lock.

  // @Immutable except that Throwable is mutable (initCause(), setStackTrace(), mutable subclasses).
  private static final class StateSnapshot {
    /**
     * The internal state, which equals external state unless shutdownWhenStartupFinishes is true.
     */
    final State state;

    /** If true, the user requested a shutdown while the service was still starting up. */

所以，下面这一行不会被执行：

```Python
    uvicorn.run(app, host="0.0.0.0", port=8000)
```

## 使用你的调试器运行代码

由于是从代码直接运行的 Uvicorn 服务器，所以你可以从调试器直接调用 Python 程序（你的 FastAPI 应用）。

例如，你可以在 Visual Studio Code 中：

* 进入到「调试」面板。
* 「添加配置...」。

## 技术细节

只是为好奇者提供的技术细节。🤓

在底层，这部分是<a href="https://asgi.readthedocs.io/en/latest/specs/lifespan.html" class="external-link" target="_blank">生命周期协议</a>的一部分，参见 ASGI 技术规范，定义了称为启动（`startup`）和关闭（`shutdown`）的事件。

包括如何处理生命周期状态，这可以用于程序的其他部分。

ASGI 기술 사양에 따르면, 이는 <a href="https://asgi.readthedocs.io/en/latest/specs/lifespan.html" class="external-link" target="_blank">Lifespan Protocol</a>의 일부이며, `startup`과 `shutdown`이라는 이벤트를 정의합니다.
