When should I use a macro instead of a generic in Rust?

Prefer generics for type abstraction and safer debugging. Use macros when you need syntax transformations, need to reduce boilerplate that generics cannot handle, or need to inspect struct fields at compile time.

How can I debug the code generated by my Rust macros?

The skill guides you through using 'cargo expand' to visualize the fully expanded Rust source code, allowing you to identify logic errors or hygiene issues in the generated output.

What are the common pitfalls in Rust macro development?

Common issues include hygiene violations where internal variables clash with user code, cryptic error messages, and significant increases in compile-time overhead if procedural macros are overused.

Does this skill help with procedural macros like #[derive]?

Yes, it provides implementation patterns for custom derive macros, attribute macros, and function-like procedural macros using standard ecosystem crates like syn and quote.

开发者工具

Streamlines Rust metaprogramming by generating and optimizing declarative and procedural macros for efficient code generation.

This skill transforms Claude into a specialized Rust metaprogramming architect, providing expert guidance on macro_rules!, procedural macros (derive, attribute, and function-like), and compile-time computation. It helps developers navigate the complexities of AST transformations using standard crates like syn and quote while ensuring macro hygiene and optimal compile-time performance. Use this skill to reduce boilerplate, build domain-specific languages, and implement complex code generation patterns that go beyond the capabilities of standard generics.
