This book is aimed at developers who have mastered the basics, and who want to take the next step to professional-level programming in Rust. Author Jon Gjengset covers everything needed to build and maintain larger code bases, write powerful and flexible applications and libraries, and confidently expand the scope and complexity of your projects.

The author takes you deep into the Rust programming language, dissecting core topics like ownership, traits, concurrency, and unsafe code. You’ll explore key concepts like type layout and trait coherence, delve into the inner workings of concurrent programming and asynchrony with async/await, and take a tour of the world of no_std programming. Gjengset also provides expert guidance on API design, testing strategies, and error handling, and will help develop your understanding of foreign function interfaces, object safety, and procedural macros.

• How to design reliable, idiomatic, and ergonomic Rust programs based on best principles
• Effective use of declarative and procedural macros, and the difference between them
• How asynchrony works in Rust – all the way from the Pin and Waker types used in manual implementations of Futures, to how async/await saves you from thinking about most of those words
• What it means for code to be unsafe, and best practices for writing and interacting with unsafe functions and traits
• How to organize and configure more complex Rust projects so that they integrate nicely with the rest of the ecosystem
• How to write Rust code that can interoperate with non-Rust libraries and systems, or run in constrained and embedded environments
