Concurrency in Rust: Asynchrony, Threads, and Parallelism

The book "Concurrency in Rust" is a comprehensive guide dedicated to one of the most powerful and complex topics in the Rust ecosystem. Rust is renowned for its ability to prevent data races and other multithreading errors at compile time, but to fully leverage these capabilities, a deep understanding of concurrency concepts is necessary.

This book will take you from the basics to advanced techniques. You will start with theory: what concurrency and parallelism are, their differences, and why Rust is uniquely suited for them. Then you will move on to practical examples written in the current version of Rust (2024).

• Fundamentals of Multithreading: creating and managing threads, transferring ownership between threads, using std::thread.
• Safe Data Sharing: mutexes (Mutex), read-write locks (RwLock), atomic operations, and reference counting with Arc.
• Channels and Message Passing: the CSP model using std::sync::mpsc and the crossbeam crate.
• Asynchronous Programming: a deep dive into async/await, tasks, Future, select!, and popular runtimes (tokio, async-std).
• Advanced Patterns: thread pools, parallel iterators (rayon), lock-free data structures, and actors.
• Profiling and Debugging: tools for finding bottlenecks, race detectors (ThreadSanitizer), and writing tests for concurrent code.

Who is this book for?

• Rust developers who want to move from sequential to multithreaded code.
• Programmers familiar with other languages (C++, Go, Java) who want to understand how Rust solves concurrency problems.
• Engineers working on high-load systems, web servers, network applications, or games.

What you will learn:

• How to avoid deadlocks, livelocks, and data races.
• When to use threads and when to use asynchrony.
• How to properly design the architecture of concurrent applications.
• How to write code that scales on multi-core processors.

All code examples are available in the repository and are accompanied by detailed comments. The book is suitable for beginners who already know the basics of Rust, as well as experienced developers looking to systematize their knowledge.
