Preface

This book is about Rust, a programming language that empowers you to build all kinds of software systems, ranging from low-level embedded software to dynamic web applications. Rust is fast, reliable, and safe. It offers performance and safety guarantees that reach or even surpass C and C++, while still being a modern language with a relatively low barrier of entry. Rust drive toward incremental improvements, combined with its active and friendly community, promises a great future for the language.

Rust is not a new language by design and doesn't try to reinvent the wheel. Rather, it's a language that has identified unique ideas, hidden away in research-prototype languages that never saw mass adoption. It brings those ideas together into a coherent composition and provides a practical language that lets you build safe software systems, while still being efficient.
