Introduction

Rust is a relatively new programming language that allows you to write fast and memory-efficient modules using modern syntax. It supports multi-platform and is also used in the world of WebAssembly and embedded systems. Notably, it has been adopted by Firefox, Dropbox, and Cloudflare.

It is also gaining attention as an alternative to C++.
