When you install Rustup you’ll also get the latest stable version of the Rust build tool and package manager, also known as Cargo. Cargo does lots of things:

• build your project with cargo build
• run your project with cargo run
• test your project with cargo test
• build documentation for your project with cargo doc
• publish a library to crates.io with cargo publish

To test that you have Rust and Cargo installed, you can run this in your terminal of choice:

cargo --version
