Starlette （和 **FastAPI**） 是基于 [AnyIO](https://anyio.readthedocs.io/en/stable/) 实现的，这使得它们可以兼容 Python 的标准库 [asyncio](https://docs.python.org/3/library/asyncio-task.html) 和 [Trio](https://trio.readthedocs.io/en/stable/)。

特别是，你可以直接使用 [AnyIO](https://anyio.readthedocs.io/en/stable/) 来处理高级的并发用例，这些用例需要在自己的代码中使用更高级的模式。

即使你没有使用 **FastAPI**，你也可以使用 [AnyIO](https://anyio.readthedocs.io/en/stable/) 编写自己的异步程序，使其拥有较高的兼容性并获得一些好处（例如， 结构化并发）。

Running `fastapi dev` initiates development mode.

By default, **auto-reload** is enabled, automatically reloading the server when you make changes to your code. This is resource-intensive and could be less stable than when it's disabled. You should only use it for development. It also listens on the IP address `127.0.0.1`, which is the IP for your machine to communicate with itself alone (`localhost`).
