Concurrent and Distributed Rust

Reactive Publishing

Concurrent & Distributed Rust is a definitive, practitioner-focused guide to building high-performance concurrent and distributed systems using Rust’s modern tooling and language guarantees. Across the book, Ethan Crossley bridges theory and real-world practice to equip developers with the architectural understanding and hands-on techniques needed to design, implement, and optimize robust systems that scale with demand.

Designed for systems programmers, backend engineers, and Rust enthusiasts with intermediate experience, this book explores the foundations of asynchronous execution in Rust and the ecosystem of async runtimes. Readers will gain a thorough understanding of how Rust’s ownership model, type system, and async/await semantics combine to deliver safe, efficient concurrency without sacrificing performance.

Key topics include:

• Understanding Rust’s async runtimes and how to choose between them for specific workloads.

• Architecting parallel workloads that maximize throughput while maintaining predictable latency.

• Techniques for building fault-tolerant, resilient distributed applications that recover cleanly from failure.

• Practical patterns for message passing, task coordination, state synchronization, and backpressure in distributed environments.

• Case studies and examples demonstrating how Rust can be applied to real-world workloads typical of cloud services, distributed databases, and scalable microservices.

This book is both a deep technical reference and a practical playbook. It bridges the gap between Rust language fundamentals and advanced system design considerations, empowering developers to harness Rust’s capabilities to build fast, scalable, and reliable systems.
