Asynchronous Rust in Action: A hands-on guide to building high-performance, scalable, and safe concurrent systems from the ground up.(Rust Programming)

If you're a developer aiming to build truly high-performance, scalable, and safe software, this guide is your direct path to mastering one of the industry's most powerful technologies. Asynchronous Rust in Action is a practical, hands-on guide that cuts through the complexity of concurrency, showing you step-by-step how to architect and build robust, parallel systems-no unnecessary theory, just the essential skills you need to build like a professional. By the end of this book, you won't just understand the theory of asynchronous Rust; you'll have applied it to build a complete, high-performance, in-memory key-value web service from the ground up, proving you have the skills to tackle complex, real-world concurrent projects. Inside, You'll Discover: Mastery of Async Fundamentals: Move beyond the basics of async/await to gain a deep, practical understanding of the Future trait, the role of the Tokio runtime, and how the entire async ecosystem works together. Safe and Modern Concurrency Patterns: Learn to manage shared state without fear. You'll move from basic mutexes to advanced, thread-safe data structures, channels, and the powerful Actor Model to prevent deadlocks and race conditions. Professional Application Architecture: Escape simple examples and learn to structure production-grade applications. You'll discover patterns for graceful error handling, clean shutdown logic, and integrating blocking code without freezing your application. The Discipline of Production-Ready Systems: Learn how to write meaningful unit and integration tests for async code, use the tracing crate to debug complex concurrent interactions, and package your application for deployment with Docker. Your First High-Performance Service: Apply every concept you've learned by building a complete key-value store with a modern web API using the Axum framework, a project that demonstrates your new professional capabilities. Why Choose This Hands-On Guide? It offers a learn-by-doing approach. You will write production-quality code and build a tangible, high-performance web service, solidifying your understanding of advanced concepts in every chapter. It is written for the practical developer. This book assumes you know the basics of Rust and focuses on filling the crucial gap between language syntax and professional, concurrent application architecture. It focuses on modern, production-grade skills. You will learn the architectural patterns and efficient workflows-like using concurrent data structures, implementing graceful shutdown, and adding monitoring with Prometheus-that are used by experienced developers to build reliable systems today. If you want a clear, direct, and rewarding path to becoming a confident builder of high-performance, concurrent Rust applications, this is the book you've been waiting for.
