Rust Application Architecture: From Design to Production

The book "Rust Application Architecture" is a practical guide for developers who want to go beyond the language syntax and learn to build reliable, performant, and scalable systems in Rust. The author, Alexey Petrov, a senior engineer with 10 years of experience in systems programming, shares proven approaches and patterns that will help you avoid common mistakes and create an architecture ready for real-world loads.

What is this book about?

The book covers the full development cycle of a Rust application: from choosing an architectural style and organizing code to deployment and monitoring in production. You will learn:

• How to apply SOLID, GRASP, and Domain-Driven Design principles in the context of Rust
• Which design patterns (Builder, State, Strategy, Visitor) fit naturally into the language's ecosystem
• How to design safe multithreaded systems using async/await and actors
• Ways to organize modules, crates, and workspaces for large projects
• How to integrate external services, databases, and message queues
• Architecture testing methods: unit, integration, and property-based tests
• Approaches to error handling, logging, and configuration
• How to perform refactoring and migration of legacy code to Rust

Who is this book for?

The book is intended for middle and senior developers who are already familiar with the basics of Rust and want to deepen their knowledge of architecture. It will be useful for:

• Backend developers building high-load services
• Systems programmers working on embedded systems and CLI tools
• Architects looking for effective ways to deal with race conditions and memory leaks
• Team leads wanting to implement best practices in their teams

What will you learn?

After reading the book, you will be able to:

• Design modular and testable applications with clear boundaries of responsibility
• Use the ownership and borrowing system to create safe architecture without a GC
• Work effectively with asynchrony, avoiding locks and deadlocks
• Build flexible systems that are easy to extend and maintain
• Make informed architectural decisions based on trade-offs between performance, safety, and convenience

Each chapter contains real code examples, diagrams, and practical exercises. The book is written in a lively style with an emphasis on practice — you will be able to immediately apply the knowledge gained in your projects. Whether you are building a web server, parser, network protocol, or embedded system, this book will be your reliable compass in the world of Rust architecture.
