Getting the most out of this book

To really grasp the content of this book, it is recommended that you write out the example code and try fiddling with code to get familiar with the Rust's error messages, so they can guide you toward writing correct programs.

There isn't any specific hardware requirements for this book, and any system with a minimum of 1 GB of RAM and a fairly recent Linux operating system would be fine. All code examples and projects in this book were developed on a Linux machine running Ubuntu 16.04. Rust also offers first-class support for other OS platforms, including macOS, BSD, and recent versions of Windows, so all the code examples should compile and run fine on these platforms too.
