## What it is
A hands-on workshop for learning to write Rust procedural macros, containing five real-world projects covering derive macros, function-like macros, and attribute macros. It was created for the Rust Latam conference and includes a test harness and guided workflow.

## Use cases
- learn to write Rust procedural macros
- practice implementing derive macros like Builder
- understand attribute macros with real examples
- find exercises for function-like macros in Rust
- get a structured tutorial on macro debugging and testing

## When to choose
- you already know Rust basics and want to learn proc macros through guided projects
- you prefer hands-on exercises with a test harness over passive reading
- you want examples drawn from real industrial use cases

## When to avoid
- you are a complete Rust beginner still learning structs, enums, and traits
- you need a production macro library rather than educational material
- you are looking for declarative macro_rules! tutorials

## Facets
- artifact type: learning-resource
- maturity: active
- function: developer-tools, compiler, testing
- domain: tutorials, programming-languages, developer-tools, education
- platform: rust, cross-platform
- tags: rust, procedural-macros, workshop, derive-macros, attribute-macros, education
