How does this skill help with Rust compiler errors?

It maps specific errors like E0277 (trait bound not satisfied) and E0038 (object safety) to design-level questions, suggesting architectural improvements rather than just quick syntax fixes.

Does this skill support object safety debugging?

Yes, it provides specific checks for object safety rules, such as identifying generic methods or 'Self' return types that prevent a trait from being used as a trait object (dyn Trait).

What is the main purpose of the m04-zero-cost skill?

It helps Rust developers decide when to use generics (static dispatch) versus trait objects (dynamic dispatch) while providing structural solutions for complex trait-related compiler errors.

When should I choose static dispatch over dynamic dispatch?

Choose static dispatch (generics) when performance is critical and types are known at compile time. Use dynamic dispatch (dyn Trait) for heterogeneous collections or to reduce compile times.

Developer Tools

Master Rust's type system to implement efficient polymorphism through generics and dynamic dispatch.

About

This skill empowers Claude to guide developers through complex Rust trait and generic implementations, focusing on the core principle of zero-cost abstractions. It provides architectural patterns for choosing between static and dynamic dispatch, resolves common compiler errors like trait bound dissatisfaction (E0277) or object safety issues (E0038), and helps optimize code for either runtime performance or binary size. By mapping specific error codes to high-level design questions, it helps transform debugging sessions into opportunities for system design improvement, ensuring your Rust abstractions are both powerful and efficient.
