Rust Getting Started


You can install rust from here. If you are on Windows, click the 64-BIT installer. I don’t know why programming languages promote 32-BIT over 64-BIT, but that’s why I’m here.


Last year I read Rust by example and it was not helpful at all at quantifying what you really need to know. My expectations is that a novice → beginner means that you are capable of producing a rust project not file that someone else can compile. Let’s skip over how to create single file projects in Rust. That’s easy, just create a file and use Code Runner in VS Code or rustc This is good for someone who is printing hello world into the console but it is a horrible way to go about things.


It doesn’t matter which IDE you use, coding in Rust is difficult either way.


Start your Rust journey by creating your very own Rust playground project. In your projects directory (wherever that may be), run

cargo init rust-playground

If cargo doesn’t work for you, you probably didn’t install Rust correctly or you didn’t restart your terminal.

Anyways, what is cargo used for? Well it’s used for managing Rust projects. Things like: building your project, using other people’s libraries in your code, and installing packages globally.

There’s more to it but this tutorial is teaching you essential basics for when things inevitably go wrong.

Writing Code

Rust does things differently. Often you will need to read documentation. The auto complete features are complete garbage as well so you need to read a lot just to write one statement.

How to print to console?

Rust has these things called macros to allow for sporadic or dynamic parameters. Thus to print something use

println!("this is a &str. What's a &str...?")


cargo run

If you see errors, use cargo run 2>cargo.log so that you have an easier time reading the errors on subsequent builds.

For release builds, use --release
