/// tip | Порада

Оскільки Pydantic серіалізуватиме це на боці **Rust**, ви отримаєте значно вищу **продуктивність**, ніж якби не оголошували тип повернення.

/// tip | Tipp

Da Pydantic es auf der **Rust**-Seite serialisiert, erhalten Sie eine deutlich höhere **Leistung**, als wenn Sie keinen Rückgabetyp deklarieren.

/// tip | Dica

Como o Pydantic fará a serialização no lado em **Rust**, você terá um desempenho muito maior do que se não declarar um tipo de retorno.

## レスポンス性能の最適化 - レスポンスモデル - 戻り値の型 { #optimize-response-performance-response-model-return-type }

JSON データを返す際の性能を最適化するには、戻り値の型またはレスポンスモデルを使用してください。そうすることで、Pydantic が Python を経由せずに Rust 側で JSON へのシリアライズを処理します。詳細は [チュートリアル - レスポンスモデル - 戻り値の型](../tutorial/response-model.md) を参照してください。

## ドキュメントのタグ - OpenAPI { #documentation-tags-openapi }

To optimize performance when returning JSON data, use a return type or response model, that way Pydantic will handle the serialization to JSON on the Rust side, without going through Python. Read more in the docs for [Tutorial - Response Model - Return Type](../tutorial/response-model.md).

반환 타입을 선언하면 FastAPI가 이를 사용해 데이터를 **검증**하고, OpenAPI에 **문서화**하고, **필터링**하고, Pydantic으로 **직렬화**합니다.

/// tip

Pydantic이 **Rust** 측에서 직렬화하므로, 반환 타입을 선언하지 않았을 때보다 훨씬 높은 **성능**을 얻게 됩니다.

### 비동기 아님 *경로 처리 함수* { #non-async-path-operation-functions }

일반 `def` 함수(`async` 없이)도 사용할 수 있으며, 동일하게 `yield`를 사용할 수 있습니다.
