重要: ジェネリクス、トレイト、ゼロコスト抽象化に関する問題に使用します。トリガー: E0277, E0308, E0599, generic, trait, impl, dyn, where, monomorphization, static dispatch, dynamic dispatch, impl Trait, trait bound not satisfied, 泛型, 特征, 零成本抽象, 单态化
Rust のジェネリクス、トレイト、ゼロコスト抽象化に関する問題に対応するスキルです。コンパイルエラー E0277、E0308、E0599 などが発生した際にトリガーされます。
このスキルは、Rust プログラミングにおけるジェネリクス（generics）、トレイト（traits）、およびゼロコスト抽象化（zero-cost abstractions）に関連する問題を解決するために設計されています。具体的には、コンパイルエラー E0277（トレイト境界未充足）、E0308（型の不一致）、E0599（メソッド未実装）などが発生した場合に自動的にトリガーされ、適切な修正方法を提案します。また、`impl Trait`、`dyn`、`where` 句、静的ディスパッチ（static dispatch）と動的ディスパッチ（dynamic dispatch）、単相化（monomorphization）など、Rust の高度な型システム機能を活用したコードの改善を支援します。このスキルは、Claude Code や Cursor などの AI エージェントプラットフォームで動作し、開発者がゼロコスト抽象化の利点を最大限に活かしながら、型安全で効率的な Rust コードを記述できるように導きます。トリガー条件には日本語のキーワード「泛型」「零成本抽象」なども含まれており、多言語の開発者に対応しています。
