/// tip

If you are in a hurry or don't care, continue with the next sections for step by step instructions to set everything up with different techniques.

また、通常の`def`*path operation関数*の中に`async def`を入れて依存関係を宣言したり、`async def`*path operation関数*の中に`def`を入れて依存関係を宣言したりすることなどができます。

それは重要ではありません。**FastAPI** は何をすべきかを知っています。

/// note | 備考

わからない場合は、ドキュメントの[Async: *"In a hurry?"*](../../async.md){.internal-link target=_blank}の中の`async`と`await`についてのセクションを確認してください。
