Building High-Performance Backends with Rust and Axum
When performance and reliability are non-negotiable for your mobile app's backend API, Rust emerges as a compelling choice. Its focus on memory safety without garbage collection, combined with near C-level speed, makes it ideal for demanding workloads. At SwissApp Group, we're increasingly adopting Rust for backend services.
We've found the Axum web framework, built on top of Tokio, Tower, and Hyper, to be a fantastic fit. Its modular design, strong type system leveraging Rust's features, and excellent performance allow us to build robust, maintainable, and incredibly fast APIs that power our clients' applications.
This post delves into our experience setting up an Axum project, structuring routes, handling requests and responses with type safety, managing database connections (e.g., with SQLx), and deploying these high-performance Rust backends effectively. We'll share some benchmarks and lessons learned along the way.
