Rust is a hugely popular, community-supported free programming language, and this book will show readers how to use Rust's robust type system to keep programs memory-safe and speedy and make the most of the Cargo package manager that brings the pieces of a program together. It covers everything from basic concepts like variable bindings, control flow, functions, and error handling, to more advanced topics, such as crates, generics, concurrency, and the nitty gritty of Rust's type system. The second edition provides expanded chapters and extra appendices.
