Fibonacci implementation in Rust

fibonacci.rs

fn main() {
	let max: uint = 25;
	let results = fibonacci(max, ~[]);

	for i in results.iter() {
		println!("{}", i.to_str());
	}
}

fn fibonacci(max: uint, mut list: ~[int]) -> ~[int] {
	if list.len() == 0 {
		list = ~[0,1];
	} else if list.len() == max {
		return list;
	}

	// Get the last two items in the list
	let f1 = *list.iter().nth(list.len() - 1).unwrap();
	let f2 = *list.iter().nth(list.len() - 2).unwrap();

	// Add them together, then add that result to the list
	list.push(f1 + f2);

	// Fibonacci-ize the list again!
	return fibonacci(max, list);
