important to us to keep Guava as easy to use and understand as we can. That means boiling
        features down to compact but powerful abstractions, and controlling feature bloat carefully.


        Guava's main yardstick for evaluating proposed features can be summed up as [utility times
        ubiquity](https://github.com/google/guava/wiki/PhilosophyExplained#utility-times-ubiquity).


        #### Utility: compare with alternatives

また、将来的にリファレンスとして機能するように構築されています。

従って、後でこのチュートリアルに戻ってきて必要なものを確認できます。

## コードを実行する

すべてのコードブロックをコピーして直接使用できます（実際にテストされたPythonファイルです）。

いずれかの例を実行するには、コードを `main.py`ファイルにコピーし、` uvicorn`を次のように起動します:

<div class="termy">

```console
$ uvicorn main:app --reload

<span style="color: green;">INFO</span>:     Uvicorn running on http://127.0.0.1:8000 (Press CTRL+C to quit)

	  {
	    return new java.net.PasswordAuthentication( System.getenv( "MVNW_USERNAME" ), System.getenv( "MVNW_PASSWORD" ).toCharArray() );
	  }
	  public static void main( String[] args ) throws Exception
	  {
	    setDefault( new Downloader() );
	    java.nio.file.Files.copy( java.net.URI.create( args[0] ).toURL().openStream(), java.nio.file.Paths.get( args[1] ).toAbsolutePath().normalize() );

    //                                                                      ==============
    /**

     *
     * @return HTML response for the failure URL list page
     */
    @Execute
    @Secured({ ROLE, ROLE + VIEW })
    public HtmlResponse index() {
        saveToken();

				writeErrorResponse(r.Context(), w, toAPIError(r.Context(), err), r.URL)
			}
			return
		}
	}

	if globalEtcdClient != nil {
		// Borrowed from
		// https://github.com/etcd-io/etcd/blob/main/etcdctl/ctlv3/command/ep_command.go#L118
		ctx, cancel := context.WithTimeout(r.Context(), defaultContextTimeout)
		defer cancel()
		if _, err := globalEtcdClient.Get(ctx, "health"); err != nil {

2. **Commits**:
   - Write clear messages: what changed and why (e.g., “Refactor S3 API handler to reduce latency so that requests process 20% faster”).
   - Rebase to tidy commits before submitting (e.g., `git rebase -i main` to squash typos or reword messages), unless multiple contributors worked on the branch.
   - Keep PRs focused—one feature or fix. Split large changes into multiple PRs.

3. **Testing**:

              <arg>-J--add-exports=jdk.compiler/com.sun.tools.javac.main=ALL-UNNAMED</arg>

### Запуск приложения

Вы можете запустить приложение следующим образом:

<div class="termy">

```console
$ fastapi dev main.py

<span style="color: green;">INFO</span>:     Uvicorn running on http://127.0.0.1:8000 (Press CTRL+C to quit)
```

</div>
