Chapter 6: Testing, Deployment, and Best Practices in Rust
Shipping reliable software is about more than compiling—it is about proving behavior, packaging polished artifacts, and operating them confidently in production. This closing chapter connects Rust's testing ergonomics to deployment pipelines so you can iterate safely from laptop to cloud.
You will reinforce correctness with layered tests, tighten release binaries, reach multiple platforms, wrap services for orchestrators, automate quality gates in CI, and measure performance when it truly matters.
