# Concurrency and async / await { #concurrency-and-async-await }

Details about the `async def` syntax for *path operation functions* and some background about asynchronous code, concurrency, and parallelism.

<abbr title="too long; didn't read"><strong>TL;DR:</strong></abbr>

If you are using third party libraries that tell you to call them with `await`, like:

```Python
results = await some_library()
```

  }

    TestGuard guard = new TestGuard(true);

`swagger_ui_parameters` は、Swagger UI に直接渡される設定を含む辞書を受け取ります。

FastAPI はそれらの設定を **JSON** に変換し、JavaScript と互換にします。Swagger UI が必要とするのはこの形式です。

## シンタックスハイライトを無効化 { #disable-syntax-highlighting }

例えば、Swagger UI のシンタックスハイライトを無効化できます。

設定を変更しなければ、シンタックスハイライトはデフォルトで有効です:

しかし、`syntaxHighlight` を `False` に設定すると無効化できます:
