Rust Macro

What it does

This skill provides access to Rust macro functionality. It allows you to generate code at compile time, reducing boilerplate and improving expressiveness within Rust programs. The skill can be used for tasks like generating repetitive code blocks or creating domain-specific languages (DSLs).

When to use it

• Automating Code Generation: You need to create similar code structures repeatedly across a project.
• Creating Custom Syntax: You want to define your own syntax and semantics within Rust, making the codebase more readable for specific tasks.
• Reducing Boilerplate: You have significant repetitive patterns in your code that can be abstracted away using macros.
• Implementing DSLs: Building a custom language or interface on top of Rust's existing features.

Key capabilities

• Code generation at compile time
• Macro definition and expansion
• Domain-Specific Language (DSL) creation
• Reducing code duplication

Example prompts

• "Generate a macro to create getter functions for a struct."
• "Write a macro that automatically implements the Debug trait for a given type."
• "Create a macro to simplify creating common data structures like linked lists."

Tips & gotchas

• Requires a basic understanding of Rust syntax and macro rules. The skill is most effective when used by developers familiar with Rust's metaprogramming capabilities.
