Note: This is a continuation of Daniel Keep's Book which has not been updated since the early summer of 2016, adapted to make use of mdBook.
This book is an attempt to distil 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.
Thanks to Daniel Keep for the original work and thanks to the following people for suggestions and corrections to the original: IcyFoxy, Rym, TheMicroWorm, Yurume, akavel, cmr, eddyb, ogham, and snake_case.
