Write Powerful Rust macrosjdk

An example driven step by step guide to success with Rust macros In Write Powerful Rust Macros you ll learn how to use these amazing metaprogramming tools to push Rust to its full potential This hands on guide takes you from the absolute basics to advanced macro techniques exploring Rust macros through interesting and engaging examples Inside Write Powerful Rust Macros you ll 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 Build your knowledge chapter by chapter You ll start with declarative macros before diving into the real procedural macros that can generate code augment data structures and even create domain specific languages About the technology Macros are one of Rust s most important and powerful tools Although notoriously challenging this metaprogramming technique has a big payoff Using macros to generate new Rust code at compile time can save you hours of tedious coding with negligible runtime performance impact This book shows you exactly how to master this Rust superpower About the book Write Powerful Rust Macros opens up the world of macros to intermediate Rust programmers You ll start with declarative macros to get the basics under your belt Then you ll advance to procedural macros as you automatically generate a builder learn to create your own domain specific languages and As you go you ll develop practical skills like testing macros integrating macros with crates and even sharing your macros with other developers What s inside How Rust libraries use macros Reading and debugging macro code newtypes and the type state pattern About the reader For intermediate Rust programmers About the author Sam Van Overmeire is an experienced Rust developer and the author of multiple books scientific articles and blog posts The technical editor on this book was Andrew Lilley Brinker Table of contents 1 Going meta 2 Declarative macros 3 A Hello World procedural macro 4 Making fields public with attribute macros 5 Hiding information and creating mini DSLs with function like macros 6 Testing a builder macro 7 From panic to Error handling 8 Builder with attributes 9 Writing an infrastructure DSL 10 Macros and the outside world Write Powerful Rust MacrosRust macros are complex when you learn the language it looks like black magic. Write Powerful Rust Macros book 2 From code generation to DSL there are so many applications for macros in rust The explanations are clear and the examples are interesting While reading it I implemented many of the techniques presented.
