The easiest way to learn Rust I've ever seen!
Rust in Action introduces the Rust programming language by exploring numerous systems programming concepts and techniques.You'll be learning Rust by delving into how computers work under the hood. You'll find yourself playing with persistent storage, memory, networking and even tinkering with CPU instructions. The book takes you through using Rust to extend other applications and teaches you tricks to write blindingly fast code. You'll also discover parallel and concurrent programming. Filled to the brim with real-life use-cases and scenarios, you'll go beyond the Rust syntax and see what Rust has to offer in real-world use cases.

About the Technology
Rust is a new systems programming language that gives you the low-level power of C with the elegance and ease of languages like Ruby and Python. Rust is thread safe, enabling "fearless concurrency". Threads are guaranteed not to overwrite each others' data, but it doesn't impose a garbage collector on you, keeping runtime performance predictable. It incorporates features from functional programming such as higher-order functions that allow for compact, readable programs. Rust is perfect for developers who want to fearlessly explore systems programming with a more ergonomic, less intimidating alternative to C or C++.What's inside
- Portability with Rust
- Concurrent and parallel programming
- Sharing resources with locks or atomic operations
- Avoiding programming with global state
- Message passing inside your applications
- Memory management and garbage collection
