Write Powerful Rust Macros

Overview

This is the code for Manning's Write Powerful Rust Macros book.

The code is organized by chapter. Exercise solutions are not located in a separate appendix directory, instead they sit next to the example code for the chapter they appeared in, and always end in -exercise. Every project besides the exercise solutions represents either a complete example, or (since many chapters are based around a single example) show stages in the development of that example. Each one contains a README file that gives some idea what part of the chapter it is related to.

Util

The util directory contains a script, create_setup.sh that allows you to generate procedural macro setups like the ones used in this book, with either 1, 2, or 3 subdirectories. All three options are explored in the book.

Usage:

./create_setup.sh name 2
