M04 Zero Cost
zhanghandong/rust-skillsZero-cost abstractions in Rust let you write fast code without slowing down. You can choose between generics and trait objects depending on your needs. This skill helps you make that choice.
When you see errors like E0277, E0308, or E0599, the skill asks the right questions. It helps you decide if you need static dispatch at compile time or dynamic dispatch at runtime. Each choice has trade-offs in performance, code size, and flexibility.
You can trace from an error back to your design. The skill also guides you to other skills for deeper work on domains, type-driven design, and performance. It is a practical tool for writing clean and fast Rust code.
