This skill equips Claude with specialized knowledge for designing, implementing, and testing various Rust macros, including macro_rules!, derive, attribute, and function-like procedural macros. It emphasizes modern best practices using the syn 2.0, quote, and proc-macro2 toolchain to ensure code hygiene, efficient compilation, and precise error reporting. It is an essential resource for developers looking to automate boilerplate, create Domain-Specific Languages (DSLs), or implement complex compile-time code generation while maintaining high code quality and testability.
