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.

Extending Cargo and tools

Cargo can also be extended to incorporate external tools for enhancing the development experience. It is designed to be as extensible as possible. Developers can create command-line tools and Cargo can invoke them via simple cargo binary-name syntax. In this section, we'll take a look at some of these tools.

Subcommands and Cargo installation

Custom commands for Cargo fall under the subcommand category. These tools are usually binaries from, GitHub, or a local project directory, and can be installed by using cargo install <binary crate name> or just cargo install when within a local Cargo project. One such example is the cargo-watch tool.
