One of the uses of a loop is to retry an operation until it succeeds. If the operation returns a value though, you might need to pass it to the rest of the code: put it after the break, and it will be returned by the loop expression.
>fn main() {
>let mut counter = 0;
>let result = loop {
>counter += 1;
>if counter == 10 {
>break counter * 2;
>}
>};
>assert_eq!(result, 20);
>}

The while keyword can be used to run a loop while a condition is true.
Let's write the infamous FizzBuzz using a while loop.
>fn main() {
>// A counter variable
>let mut n = 1;
>// Loop while `n` is less than 101
>while n < 101 {
>if n % 15 == 0 {
>println!("fizzbuzz");
>} else if n % 3 == 0 {
>println!("fizz");
>} else if n % 5 == 0 {
>println!("buzz");
>} else {
>println!("{}", n);
>}
>// Increment counter
>n += 1;
>}
>}
