Convert Rust strings to numbers using the .parse() method and handle errors with match or expect.

Use the .parse() method on your string to convert it into a number, handling the resulting Result with a match expression or .expect(). This approach is standard in Rust for converting user input or string data into numeric types like u32.

let input = "42";
let number: u32 = match input.trim().parse() {
    Ok(num) => num,
    Err(_) => panic!("Please type a number!"),
};
