### 당신만의 비동기 코드 작성하기

Starlette(그리고 FastAPI)는 <a href="https://anyio.readthedocs.io/en/stable/" class="external-link" target="_blank">AnyIO</a>를 기반으로 하고있고, 따라서 파이썬 표준 라이브러리인 <a href="https://docs.python.org/3/library/asyncio-task.html" class="external-link" target="_blank">asyncio</a> 및 <a href="https://trio.readthedocs.io/en/stable/" class="external-link" target="_blank">Trio</a>와 호환됩니다.

    String LOGGING_SEARCH_DOCS_ENABLED = "logging.search.docs.enabled";

    /** The key of the configuration. e.g. filetype,created,click_count,title,doc_id,url,score,site,filename,host,digest,boost,mimetype,favorite_count,_id,lang,last_modified,content_length,timestamp */

では、このニワトリと卵の問題について、最初の `async` 関数をどのように呼び出すのでしょうか？

**FastAPI**を使用している場合、その「最初の」関数が*path operation 関数*であり、FastAPIが正しく実行する方法を知っているので、心配する必要はありません。

しかし、FastAPI以外で `async` / `await` を使用したい場合は、<a href="https://docs.python.org/3/library/asyncio-task.html#coroutine" class="external-link" target="_blank">公式Pythonドキュメントを参照して下さい</a>。

### 非同期コードの他の形式

`async` と `await` を使用するスタイルは、この言語では比較的新しいものです。

非同期コードの操作がはるかに簡単になります。

    // While MockWebServer waits to read the client's HEADERS frame before sending the response, it
    // doesn't wait to read the client's DATA frame and may send a DATA frame before the client
    // does. So we can't assume the client's empty DATA will be logged first.
    assertThat(countFrames(logs, "FINE: >> 0x00000003     0 DATA          END_STREAM"))
      .isEqualTo(1)

    assertThat(i.hasNext()).isTrue()

    // ...so even when we evict the element, we still get something back.
    cache.evictAll()
    assertThat(i.next()).isEqualTo(url.toString())

    // Remove does nothing. But most importantly, it doesn't throw!
    i.remove()
  }
