Master professional-level coding in Rust. Intermediate Rust is a next-steps book for Rust developers who've mastered the basics, covering everything you need to build and maintain larger, more complex code bases. Author Jon Gjengset digs deep into the Rust language and standard library, dissecting topics like ownership, traits, lifetimes, concurrency, and unsafe and asynchronous code, with an eye towards developing working understanding and real-world applicability. The book focuses on how the language works, and aims to give you the insights you need to write more ergonomic, higher performance Rust programs. You'll also learn the ins and outs of macros, foreign function interfaces, and no-std development for those more finicky use-cases. By the end, you should be able to build out your programs in size, scope, and complexity with confidence.
