Setting up your environment

Since the programming language comes with a variety of toolchains, tools, linkers, and compiler versions, choosing the best-fitting variation is not easy. Additionally, Rust works on all major operating systems—which adds another variable. 

However, installing Rust has become a trivial task when using rustup (https://rustup.rs/). On the website, a helpful script (or installer on Windows) that takes care of retrieving and installing the required components can be downloaded. The same tool lets you switch between and update (and uninstall) these components as well. This is the recommended way.

To write code, an editor is also required. Since Visual Studio Code sports some Rust parts, it is a great choice together with the Rust extension. It's an open source editor developed by Microsoft and is well received across the world and the Rust community. In this recipe, we will install the following components:

• Visual Studio Code (https://code.visualstudio.com/)
• rustup (https://rustup.rs)
• rustc (and the rest of the compiler toolchains)
• cargo
• RLS (short for Rust Language Server—this is for autocompletion)
• Rust language support for Visual Studio Code
