        the time to discuss them in detail will make it much clearer why this feature should be
        added to Guava.

        feature and its potential value for other Guava users.

///

/// tip

Remember that in most of the cases, when something is required, you can simply omit the default, so you normally don't have to use `...`.

///

* 次に、ミドルウェアはアプリケーション (の *path operation*) によって生成された**レスポンス**を受け取ります。
* その**レスポンス**に対して何かを実行したり、必要なコードを実行したりできます。
* そして、**レスポンス**を返します。

/// note | "技術詳細"

`yield` を使った依存関係をもつ場合は、終了コードはミドルウェアの *後に* 実行されます。

バックグラウンドタスク (後述) がある場合は、それらは全てのミドルウェアの *後に* 実行されます。

## ミドルウェアの作成

ミドルウェアを作成するには、関数の上部でデコレータ `@app.middleware("http")` を使用します。

ミドルウェア関数は以下を受け取ります:

We have 3 different things that we synchronize on.

#### Http2Connection

This lock guards internal state of each connection. This lock is never held for blocking operations. That means that we acquire the lock, read or write a few fields and release the lock. No I/O and no application-layer callbacks.

#### Http2Stream
