Understand how to handle errors gracefully in Rust by using the Result enum for functions that can return errors.

fn divide(a: f64, b: f64) -> Result<f64, &'static str> {
    if b == 0.0 {
        Err("Division by zero is not allowed")
    } else {
        Ok(a / b)
    }
}

fn main() {
    let result = divide(10.0, 2.0);
    match result {
        Ok(value) => println!("Result: {}", value),
        Err(err) => println!("Error: {}", err),
    }
}
