Rust is not a new language by any means, but it’s getting plenty of attention lately. As you might’ve heard, it’s a relatively low-level systems programming language. Similar to golang in a sense, with a completely different approach to memory management.
Apart from the classical use cases, I really like using Rust to make fast, super-portable CLI tools that are easy to package in a container. A compiled binary is a lot easier to handle than something like a Python-based tool with a ton of dependencies.
For a systems programming language, Rust is surprisingly rich in features. Pattern matching, Option, and Result types, who knew? This power comes at the cost of complexity. Rust is definitely not a simple language, which is why this book clocks at 500 pages. The borrow checker is very different from anything you’ve seen before, and you’ll have to re-read that chapter over and over until you start making sense of the concept. Lifetimes are pretty tricky as well. By the time things like multi-threading came around, I was pretty overwhelmed.
Luckily, this book is an excellent reference to navigate all these ideas. And it covers the ecosystem as well, which is a nice plus. You’ll learn about cargo, its build system, and package manager. Testing makes an appearance, which is great news for all the TDD lovers.
All in all, if you want to get started understanding Rust, this book is an excellent starting point. It won’t be the last one you read if you’re going to get a deeper understanding of the whole thing.
Verdict
This is a comprehensive book, not only introducing the language but the ecosystem as well. The only thing I missed was going a bit more into the community’s best practices and established conventions. Although to be fair, it’s already a pretty long book as it’s. It gets ⭐⭐⭐⭐ stars from me.

I might give this a go later then 😅
