Professional Rust: Advanced Techniques

The book "Professional Rust: Advanced Techniques" is a practical guide for developers who have already mastered the basics of the Rust language and want to reach the next level. The author, Alexey Voronov, an engineer with many years of experience in systems programming, shares deep knowledge and proven techniques that will help you create high-performance and reliable applications.

What is this book about?

The book is dedicated to the advanced capabilities of Rust, which often remain outside the scope of introductory courses. You will dive into the following topics:

• Safe and unsafe code: when and how to use unsafe without violating Rust's safety guarantees, and how to minimize risks.
• Interaction with C and other languages (FFI): creating bindings for native libraries, working with raw pointers, and managing memory across language boundaries.
• Asynchronous programming: a deep dive into the async/await model, futures, state machines, and efficient runtimes (tokio, async-std).
• Macros and metaprogramming: from declarative macros to procedural macros — automating routine tasks and generating code.
• Build systems and testing: advanced work with Cargo, custom test frameworks, and benchmarks.
• Design patterns: idiomatic solutions for complex problems, including type-safe state machines and dependency injection.

Who is this book for?

The publication is intended for:

• Developers who have already written several projects in Rust and want to learn its inner workings.
• Engineers transitioning from C/C++ to Rust and looking for ways to maintain performance without losing safety.
• Systems programming specialists working on embedded systems, games, browsers, or high-load servers.
• Anyone who wants to understand how popular crates are built and how to create their own advanced libraries.

What will you learn?

After reading the book, you will be able to:

• Write efficient unsafe code without sacrificing reliability.
• Integrate Rust with existing C libraries and create your own FFI bindings.
• Design asynchronous systems that are resilient to load and errors.
• Use macros to reduce boilerplate code and create DSLs.
• Apply advanced types such as GAT (generic associated types) and type alias impl Trait.
• Optimize performance using profiling and low-level tricks.

Each chapter contains numerous code examples that can be run and modified immediately. The book is written in a lively style, with an emphasis on practice rather than dry theory. If you want to become a Rust expert and learn to use its full potential, this guide will be your reliable companion.
