Declarative Macros in Rust: A Simple and Practical Introduction
Learn the basics of Rust declarative macros! Understand the syntax, learn the terminology, explore macro hygiene, and master fragment specifiers.
Hey everyone!
I'm back with another article focused on Rust fundamentals. I think existing material covers the basics of using Rust pretty well, but one thing that I found kind of lacking back when I learned Rust was description of macros.
It's possible it has improved nowadays, but I want to eventually write about proc-macros. So I'm going to start with an article introducing the concept of macros, and explaining the differences between Rust and C-style macros, as well as the basics of declarative macros.
Future articles will eventually get into procedural macro territory. But I want to move through this slowly and carefully.
Anyways, I hope this helps if you are new to Rust and struggling to understand the macro_rules! syntax (or just anything about Rust macros, really).
If you have questions or feedback for future articles, please let me know.
