## Recap { #recap }

You can now get the current user directly in your *path operation function*.

We are already halfway there.

We just need to add a *path operation* for the user/client to actually send the `username` and `password`.

        double avgOpTimeNs = totalTime.get() / (double) operations.get();

        System.out.printf("Encryption Byte Tracking Performance: %d ops in %.2f ms%n", operations.get(), overallTimeMs);
        System.out.printf("  Avg atomic operation time: %.2f ns%n", avgOpTimeNs);

        // Verify lock-free performance (allowing for JVM overhead)
        assertTrue(avgOpTimeNs < 5000, "Atomic operations should be reasonably fast (no lock contention)");

which are made up of goroutine executions,
which in turn are made up of memory operations.
</p>

<p>
A <i>memory operation</i> is modeled by four details:
</p>
<ul>
	<li>its kind, indicating whether it is an ordinary data read, an ordinary data write,
    or a <i>synchronizing operation</i> such as an atomic data access,
	a mutex operation, or a channel operation,</li>
	<li>its location in the program,</li>

## 簡単な使い方

見てみると、*path*と*operation*が一致した時に*path operation関数*が宣言されていて、**FastAPI** が正しいパラメータで関数を呼び出してリクエストからデータを抽出する処理をしています。

実は、すべての（あるいはほとんどの）Webフレームワークは、このように動作します。

これらの関数を直接呼び出すことはありません。これらの関数はフレームワーク（この場合は、**FastAPI**）によって呼び出されます。

依存性注入システムでは、**FastAPI** に*path operation*もまた、*path operation関数*の前に実行されるべき他の何かに「依存」していることを伝えることができ、**FastAPI** がそれを実行し、結果を「注入」することを引き受けます。

    /**
     * Inner thread class for executing data store crawling operations.
     * Each thread handles crawling for a single data configuration,
     * processing documents and updating the search index.
     *
     * <p>The thread manages:</p>
     * <ul>
     *   <li>Data store initialization and document processing</li>
     *   <li>Index update operations through callbacks</li>
     *   <li>Error handling and failure logging</li>

## Declare scopes in *path operations* and dependencies { #declare-scopes-in-path-operations-and-dependencies }

Now we declare that the *path operation* for `/users/me/items/` requires the scope `items`.

For this, we import and use `Security` from `fastapi`.
