Starlette (and **FastAPI**) are based on [AnyIO](https://anyio.readthedocs.io/en/stable/), which makes it compatible with both Python's standard library [asyncio](https://docs.python.org/3/library/asyncio-task.html) and [Trio](https://trio.readthedocs.io/en/stable/).

In particular, you can directly use [AnyIO](https://anyio.readthedocs.io/en/stable/) for your advanced concurrency use cases that require more advanced patterns in your own code.

 * [application interceptor][OkHttpClient.interceptors] or as a [OkHttpClient.networkInterceptors].
 *
 * The format of the logs created by this class should not be considered stable and may
 * change slightly between releases. If you need a stable logging format, use your own interceptor.

* **Third-party APIs and libraries**: When integrating with external APIs that use different spelling conventions
* **Historical compatibility**: Existing public API methods that are part of Gradle's stable API cannot be renamed due to backward compatibility requirements (though new APIs should use American English)
* **Proper nouns and quotes**: Names of organizations, products, or quoted text that use different conventions

And integrate standards-based user interface tools:

* [Swagger UI](https://github.com/swagger-api/swagger-ui)
* [ReDoc](https://github.com/Rebilly/ReDoc)

These two were chosen for being fairly popular and stable, but doing a quick search, you could find dozens of alternative user interfaces for OpenAPI (that you can use with **FastAPI**).

### Flask REST frameworks { #flask-rest-frameworks }

Starlette(그리고 **FastAPI**)는 [AnyIO](https://anyio.readthedocs.io/en/stable/)를 기반으로 하고 있으며, 파이썬 표준 라이브러리 [asyncio](https://docs.python.org/3/library/asyncio-task.html)와 [Trio](https://trio.readthedocs.io/en/stable/) 모두와 호환됩니다.

특히, 코드에서 더 고급 패턴이 필요한 고급 동시성 사용 사례에서는 직접 [AnyIO](https://anyio.readthedocs.io/en/stable/)를 사용할 수 있습니다.

        String actual = blob.toString();

        // Assert
        assertEquals(expected, actual, "Hex string should match expected format");
    }

    // Ensures a default-constructed blob starts empty and stable across APIs
    @Test
    @DisplayName("Default constructor yields empty state")
    void defaultConstructor_initialState() {
        // Arrange & Act
        SecurityBlob blob = new SecurityBlob();

        // Assert

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`).

## `fastapi run` { #fastapi-run }

Starlette（和 **FastAPI**）是基於 [AnyIO](https://anyio.readthedocs.io/en/stable/) 實作的，這使得它們與 Python 標準函式庫 [asyncio](https://docs.python.org/3/library/asyncio-task.html) 和 [Trio](https://trio.readthedocs.io/en/stable/) 相容。

特別是，你可以直接使用 [AnyIO](https://anyio.readthedocs.io/en/stable/) 來處理更複雜的並行使用案例，這些案例需要你在自己的程式碼中使用更高階的模式。

即使你不使用 **FastAPI**，你也可以使用 [AnyIO](https://anyio.readthedocs.io/en/stable/) 來撰寫自己的非同步應用程式，並獲得高相容性及一些好處（例如「結構化並行」）。
