1 Introducing Rust
This chapter covers:
- Introducing Rust’s features and goals
- Exposing Rust’s syntax
- Discussing where to use Rust and when to avoid it
- Building your first Rust program
- Explaining how Rust compares to object-oriented and wider languages
“Welcome to Rust — the empowering programming language. Once you scratch its surface, you will not only find a programming language with unparalleled speed and safety, but one that is enjoyable enough to use every day.” (RiA1)
“When you begin to program in Rust, it’s likely that you will want to continue to do so. And this book, Rust in Action, will build your confidence as a Rust programmer. But it will not teach you how to program from the beginning. This book is intended to be read by people who are considering Rust as their next language and for those who enjoy implementing practical working examples. Here is a list of some of the larger examples this book includes:” (RiA1)
- Mandelbrot set renderer
- A grep clone
- CPU emulator
- Generative art
- A database
- HTTP, NTP, and hexdump clients
- LOGO language interpreter
- Operating system kernel
“As you may gather from scanning through that list, reading this book will teach you more than just Rust. It also introduces you to systems programming and low-level programming. As you work through Rust in Action, you’ll learn about the role of an operating system (OS), how a CPU works, how computers keep time, what pointers are, and what a data type is. You will gain an understanding of how the computer’s internal systems interoperate. Learning more than syntax, you will also see why Rust was created and the challenges that it addresses.” (RiA1)
