Systems programming provides the foundation for the world's computation. Developing performance-sensitive code requires a programming language that puts programmers in control of how memory, processor time, and other system resources are used. The Rust systems programming language combines that control with a modern type system that catches broad classes of common mistakes, from memory management errors to interthread data races.

With this practical guide, experienced systems programmers will learn how to successfully bridge the gap between performance and safety using Rust. Jim Blandy, Jason Orendorff, and Leonora Tindall demonstrate how Rust's features put programmers in control over memory consumption and processor use by combining predictable performance with memory safety and trustworthy concurrency.

Rust is a language for systems programming. Systems programming is for:

• Operating systems
• Device drivers of all kinds
• Filesystems
• Databases
• Code that runs in very cheap devices, or devices that must be extremely reliable
• Cryptography
• Media codecs (software for reading and writing audio, video, and image files)
• Media processing (for example, speech recognition or photo editing software)
• Memory management (for example, implementing a garbage collector)
• Text rendering (the conversion of text and fonts into pixels)
• Implementing higher-level programming languages (like javascript and Python)
• Networking
• Virtualization and software containers
• Scientific simulations
• Games

In short, systems programming is resource-constrained programming. It is programming when every byte and every CPU cycle counts.
The amount of systems code involved in supporting a basic app is staggering. This book will not teach you systems programming. In fact, this book covers many details of memory management that might seem unnecessarily abstruse at first, if you haven’t already done some systems programming on your own. But if you are a seasoned systems programmer, you’ll find that Rust is something exceptional: a new tool that eliminates major, well-understood problems that have plagued a whole industry for decades.

You'll learn:

Rust's fundamental data types and the core concepts of ownership and borrowing

Language basics including error handling, crates and modules, structs, and enums

How to write flexible, efficient code with traits and generics

Rust's key power tools: closures, iterators, and asynchronous programming

Collections, strings and text, input and output, concurrency, macros, unsafe code, and interfacing with foreign functions

Who Should Read This Book:
If you’re already a systems programmer and you’re ready for an alternative to C++, this book is for you. If you’re an experienced developer in any programming language, whether that’s C#, Java, Python, javascript, or something else, this book is for you too. However, you don’t just need to learn Rust. To get the most out of the language, you also need to gain some experience with systems programming. We recommend reading this book while also implementing some systems programming side projects in Rust.
