This book is an attempt to distill the Rust community's collective knowledge of Rust macros,
Macros by Example to be precise. As such, both additions (in the form of pull requests) and
requests (in the form of issues) are welcome.
The original Little Book of Rust Macros has helped me
immensely with understanding Macros by Example style macros while I was still learning the
language. Unfortunately, the author of the book has since left the project untouched, while the Rust
language as well as it's macro-system keeps evolving. Which is why I wanted to revive the project
and keep it up to date with current Rust helping other newcomers understand macros, a part of the
language a lot of people seem to have trouble with.
This book expects you to have basic knowledge of Rust, it will not explain language features or constructs that are irrelevant to macros. No prior knowledge of macros is assumed. Having read and understood the first seven chapters of the Rust Book is a must, though having read the majority of the book is recommended.
