You can use the same type declarations with `str`, `float`, `bool` and many other complex data types.

Several of these are explored in the next chapters of the tutorial.

## Order matters { #order-matters }

When creating *path operations*, you can find situations where you have a fixed path.

///

/// check | 確認

依存関係システムがこのように設計されているおかげで、 `User` モデルを返却する別の依存関係（別の「dependables」）を持つことができます。

同じデータ型を返却する依存関係は一つだけしか持てない、という制約が入ることはないのです。

///

## 別のモデル { #other-models }

これで、*path operation 関数* の中で現在のユーザーを直接取得し、`Depends` を使って、 **依存性注入** レベルでセキュリティメカニズムを処理できるようになりました。

そして、セキュリティ要件のためにどんなモデルやデータでも利用することができます。（この場合は、 Pydanticモデルの `User`）

しかし、特定のデータモデルやクラス、型に制限されることはありません。

				// to rebalance, just skip it, this also includes
				// any other versions that have already expired.
				remainingVersions := len(fivs.Versions) - expired
				if version.Deleted && remainingVersions == 1 {
					rebalanced++
					stopFn(version.Size, errors.New("DELETE marked object with no other non-current versions will be skipped"))
					continue
				}

				versionID := version.VersionID

Такий стиль використання `async` і `await` відносно новий у мові.

Але він значно полегшує роботу з асинхронним кодом.
