Rust and Databases: A Practical Guide

The book "Rust and Databases: A Practical Guide" is a comprehensive resource for developers who want to master integrating the Rust language with relational databases. Unlike abstract tutorials, the book offers ready-made solutions for real projects: from simple configuration storage in SQLite to high-load systems on PostgreSQL with asynchronous queries.

The author consistently guides the reader from basics to advanced topics. You will learn how to set up a connection, perform CRUD operations, work with migrations and transactions. Special attention is paid to type safety — Rust's strong point. You will learn to design data schemas that the compiler checks at build time, eliminating an entire class of runtime errors.

Who this book is for:

• Rust developers who want to add database work to their toolkit
• Backend engineers migrating from other languages (Python, Go, Java) to Rust
• Students and teachers studying systems programming and data storage
• Professionals working on high-load and secure systems

What you will learn:

• Basics of working with SQLite via the rusqlite library — from creating tables to complex queries
• Full interaction with PostgreSQL via tokio-postgres and sqlx in asynchronous mode
• Using the Diesel ORM: schema definition, migrations, complex table relationships
• Connection pooling, error handling, transactions, and data isolation
• Application architecture: repositories, service layer, testing with databases
• Performance: indexes, query optimization, profiling

The book contains over 20 practical examples with complete code, ready for use in your projects. Each chapter ends with exercises to reinforce the material. All examples are tested on current versions of Rust (1.70+) and are compatible with the latest stable releases of the libraries.

"Rust and Databases" is not just a reference guide, but a navigator for building reliable backends. You will stop fearing database work in Rust and start enjoying the rigor and performance of this language.
