Mastering Rust. - Second Edition

By: Rahul Sharma

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.

Setting up a Rust development environment

Rust has decent support for most code editors out there, whether it be vim, Emacs, intellij IDE, Sublime, Atom, or Visual Studio Code. Cargo is also well supported by these editors, and the ecosystem has several tools that enhance the experience, such as the following:

  • rustfmt: It formats code according to conventions that are mentioned in the Rust style guide.
  • clippy: This warns you of common mistakes and potential code smells. Clippy relies on compiler plugins that are marked as unstable, so it is available with nightly Rust only. With rustup, you can switch to nightly easily.
  • racer: It can do lookups into Rust standard libraries and provides code completion and tool tips.

Among the aforementioned editors, the most mature IDE experience is provided by Intellij IDE and Visual Studio Code (vscode). We will cover setting up the development...
