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 Rust Power Tools 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
Rust Power Tools 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.
about the book
Rust Power Tools is a comprehensive guide to creating macros in Rust. You’ll start your journey with declarative macros, then quickly move on to the powerful procedural macros to build your own domain-specific language. Learn how to create public fields, work with custom attributes, integrate your macros with other crates, write effective tests to ensure your macros are reliable and bug-free, and even share your macros with other developers.
Among the many powerful tools that Rust has to offer, macros are some of the most important and common. They serve as "a light in dark places, when all other lights go out", to be used when normal tools don’t suffice. That of itself is enough to make macros a core topic of this book. They have another neat quality though: they can be a "`pathway to many abilities`", as the emperor would put it. When you want to write a macro, you need knowledge of testing and debugging. You have to know how to set up a library because you cannot write a procedural macro without creating a library. Some knowledge about Rust internals, compilation, types, code organization, pattern matching, parsing… also comes in handy. Thus learning about macros allows me to talk about a variety of other programming topics! So we will be learning about Rust macros and using them to explore other subjects. Procedural macros, specifically, will take center stage because they are powerful and versatile… and you can already find a lot of useful content on declarative macros!
