Get ready to code like a pro in Rust! This hands-on guide dives deep into memory management, asynchronous programming, and Rust design patterns and explores essential productivity techniques like testing, tooling, and project management.

Code Like A Pro in Rust is a fast-track guide to building and delivering professional quality software in Rust. You’ll upgrade your basic knowledge of Rust with conventions, best practices, and veteran’s secrets that are normally only learned through years of experience. Skip the fluff and get right to the heart of this powerful modern language, including Rust’s support for asynchronous programming and integrating Rust with codebases written in other languages.

Purchase of the print book includes a free eBook in PDF, Kindle, and ePub formats from Manning Publications.
