Programming with Rust

Rust's exciting innovations have made it the most loved programming language in Stack Overflow's influential survey for five straight years--but its steep learning curve has made many other developers reluctant to dive in. Now, with a growing commitment to Rust from many of the world's leading development organizations, it's the perfect time to start--especially now that there's an up-to-date, accessible, example-rich book to guide you. Long-time enterprise developer Donis Marshall has made Rust easier to understand than ever, with a guide expertly organized into short, bite-sized chapters and supported with focused video tutorials that bring you up-to-speed fast. Writing for developers at all levels, Marshall starts with the absolute basics, and thoroughly demystifies the Rust technical advances that make it so attractive for next-generation development. Everything's here, from types and assignments to ownership, lifetimes, traits, and crates. Marshall even offers indispensable expert advice for unit testing, handling unsafe code, interoperating with legacy code bases, and using Rust's increasingly robust tools. More than just a new language, Rust represents a philosophical shift in how you code. With Programming in Rust, you'll master the techniques and the mindset, make Rust a key tool in your arsenal, and access one of the industry's fastest-growing areas of opportunity.
