Supercharge your code with macros—the real power tools of the Rust programming language!

Macros are instructions to generate new Rust code at compile-time, saving you hours of tedious code writing. The top Rust developers have built macros into everything from the standard library to crates. Now you can learn how these amazing “power tools” will help you push Rust to its full potential. This hands-on guide takes you from the absolute basics to advanced macro techniques.

Inside Write Powerful Rust Macros you’ll discover:

• Writing declarative macros
• Procedural macros
• Reading and debugging macro code
• Improving the type system with newtypes and zero-sized types
• How common Rust libraries use macros

Write Powerful Rust Macros teaches you how to write, test, debug, and publish macros for Rust. It’s perfect for Rust practitioners who want to master this powerful development technique. In this unique book, you’ll explore Rust macros through interesting and engaging examples, including automatically generating a ‘builder’ and composing a DSL for writing Infrastructure as Code.

Purchase of the print book includes a free eBook in PDF and ePub formats from Manning Publications.
