返すべき以上のデータを返さないようにするには、[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。

## 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。
