Mastering Rust - Second Edition

By: Rahul Sharma, Vesa Kaihlavirta

Overview of this book

Rust is an empowering language that provides a rare combination of safety, speed, and zero-cost abstractions. Mastering Rust – Second Edition is filled with clear and simple explanations of the language features along with real-world examples, showing you how you can build robust, scalable, and reliable programs. This second edition of the book improves upon the previous one and touches on all aspects that make Rust a great language. We have included the features from latest Rust 2018 edition such as the new module system, the smarter compiler, helpful error messages, and the stable procedural macros. You’ll learn how Rust can be used for systems programming, network programming, and even on the web. You’ll also learn techniques such as writing memory-safe code, building idiomatic Rust libraries, writing efficient asynchronous networking code, and advanced macros. The book contains a mix of theory and hands-on tasks so you acquire the skills as well as the knowledge, and it also provides exercises to hammer the concepts in. After reading this book, you will be able to implement Rust for your enterprise projects, write better tests and documentation, design for performance, and write idiomatic Rust code.

If you are already finding macros empowering, here are some exercises for you to try so that you can tinker with macros some more:

  1. Write a macro that accepts the following language:
        language = HELLO recipient;
recipient = <String>;

For instance, the following strings would be acceptable in this language:

        HELLO world!
HELLO Rustaceans!

Make the macro generate code that outputs a greeting that's directed to the recipient.

  1. Write a macro that takes an arbitrary number of elements and outputs an unordered HTML list in a literal string, for instance, html_list!([1, 2]) => <ul><li>1/<li><li>2</li></ul>.
