Return: Quiz IV in Rust

Quiz: What would this code produce if we were to copy-paste it in a code editor and run it?

fn greet_and_return() -> String {
    return "How are you doing?".to_string();
    println!("Hey bro!");
}

fn main_function() {
    let question = greet_and_return();
    println!("{}", question);
}

Important Note:

Do not use an actual code editor to get the answer! It would defy the whole purpose of the quiz!
