Setup

The best way to set up and maintain a Rust installation is to use the rustup tool.

If you're running Linux, it's a one-line command. Run this, and follow the prompts:

curl --proto '=https' --tlsv1.2 -sSf https://sh.rustup.rs | sh

If you are installing in Windows, you may also need to install the Visual Studio Build Tools. The rustup CLI will prompt you if this is the case.

After you've installed Rust, you can update to the latest version at any time by running rustup update.

After rustup finishes, test your installation by running rustc --version. You should see something like this:

rustc 1.63.0 (4b91a6ea7 2022-08-08)

If you'd like to actually test the compiler, create a file named main.rs, with the following contents:

fn main() {
	println!("Hello, world!");
}

Then, run this:

rustc main.rs

This will produce a binary file called main. When you run it, you should see this:

Hello, world!
