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 a new level of mastery. Author Alexey Sokolov, an engineer with experience in embedded systems and high-load services, shares techniques that are rarely found in beginner tutorials but are essential for creating production solutions.

What is this book about?

The publication focuses on four key areas:

• Safe and unsafe code: how to correctly use unsafe blocks without violating Rust's safety guarantees; working with raw pointers and manual memory management.
• FFI and C interop: creating safe wrappers over C libraries, exporting Rust functions for other languages, working with ABI and linking.
• Advanced async: building your own runtime, working with Future, Pin, Waker; writing efficient async I/O drivers.
• Macros and metaprogramming: procedural macros from simple derive to full-fledged DSLs; code generation and compile-time optimization.

Who is this book for?

The book is intended for:

• Developers who have already written several projects in Rust and want to understand the inner workings of the language.
• Engineers working on system software, databases, game engines, or embedded systems.
• Those transitioning from C/C++ and wanting to use Rust for tasks requiring low-level control.
• Programmers interested in async runtimes, FFI, and performance optimization.

What will you learn?

• How to design safe abstractions over unsafe code.
• How to integrate Rust code with existing C libraries and vice versa.
• How to create your own async primitives and runtime.
• How to write procedural macros that save hours of routine work.
• How to profile and optimize the performance of Rust applications.
• Architectural patterns for large projects: modularity, testing, error handling.

Each chapter contains real code examples, analysis of common mistakes, and exercises to reinforce the material. The book is not overloaded with theory — the emphasis is on practice and understanding how Rust's mechanisms work under the hood.

"Professional Rust" is not just a reference book, but a navigator through complex topics that distinguish a beginner from an expert. After reading it, you will be able to confidently take on tasks that require full control over memory, performance, and safety.
