Rust Playground

In addition to running and editing code in the browser, you might find the Rust Playground helpful. It's a web interface for running Rust code.

fn main() {
    println!("Welcome to Fast Track to Rust!");
}

Exercise

• Hover the mouse over the code block and click the arrow button to run the code.
• Modify the "Welcome to Fast Track to Rust!" string and re-run the code.
• Revert your changes by hovering your mouse over the code block and clicking the Undo changes button.
• Run the hello world program in the playground.
