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.

Summary

In this chapter, we explored a lot about building web applications with Rust and how easy it is to get started, given the high-quality crates that are available to us. Being a compiled language, web applications written in Rust are many times smaller than other frameworks that are written in dynamic languages. Most of the web framework space is dominated by interpreted dynamic languages that can hog a lot of CPU but aren't very resource-efficient. However, people use them because web applications are very convenient to write with them.

Web applications that are written with Rust take up a lot less space at runtime. Rust also takes up less memory during runtime, as no interpreter is needed, as is the case with dynamic languages. With Rust, you get the best of both worlds, that is, the same feel of dynamic languages while at the same time being performant, like C. This...
