Async Rust: The Complete Guide

"Async Rust: A Complete Guide" is a practical guide that will help you master one of the most powerful yet most complex topics in the Rust ecosystem. The book will take you from the basic principles of asynchrony to building real-world industrial applications using the Tokio framework.

In today's world, where response speed and efficient resource utilization are critical, asynchronous programming is becoming a mandatory skill for Rust developers. This book provides not just theory, but a deep understanding of how async runtimes, schedulers, and execution models work.

Who this book is for

• Developers already familiar with Rust basics who want to move on to building high-load services
• Systems programmers who want to understand the internal workings of async runtimes
• Engineers building network applications, web servers, chats, and proxies in Rust
• Anyone who wants to write fast and reliable async code without data races and deadlocks

What you will learn from this book

• Complete understanding of async/await, Futures, and streams
• Tokio runtime internals: Executor, Reactor, Waker
• Async primitives: Mutex, RwLock, channels (mpsc, broadcast, oneshot)
• Timers, intervals, and working with time in async code
• Building TCP/UDP servers and clients from scratch
• Error handling and task cancellation in an async context
• Profiling, benchmarking, and debugging async applications
• Advanced techniques: pin, select!, join!, stream abstractions
• Integration with synchronous code via spawn_blocking
• Design patterns for scalable network services

Each chapter contains practical examples that can be immediately applied in projects. You will learn to write async code that is not only functional but also easy to maintain, scale, and optimize.

The book is suitable for self-study: from your first async functions to complex multi-threaded architectures. You will gain the skills necessary to work on real-world projects in the fields of high-load systems, microservices, and network infrastructure.

Master async Rust — and you will be able to create applications that make the most efficient use of CPU and memory resources while ensuring high performance and fault tolerance.
