Rust in Action

Rust in Action by Tim McNamara is a hands-on systems programming book that teaches Rust by walking you through concrete, real-world projects. You’ll explore how computers work under the hood—memory, CPU instructions, networking, file I/O—and apply Rust to build things like a CPU emulator, a database, DNS resolver, and even parts of an OS kernel. Along the way you’ll also learn Rust’s features for safety, concurrency, and performance, making it more than just a language tutorial: it’s a bridge from systems programming theory to practical Rust code.
