Return: Quiz I in Rust in Rust

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

fn get_double(n: i32) -> i32 {
	n * 2;
}

fn main_function() {
	let result = get_double(10);
	println!("{}", result);
}

Important Note:

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