Nesting and labels - Rust By Example
Description: Rust by Example (RBE) is a collection of runnable examples that illustrate various Rust concepts and standard libraries.

# Nesting and labels

It's possible to `break` or `continue` outer loops when dealing with nested loops. In these cases, the loops must be annotated with some `'label`, and the label must be passed to the `break`/`continue` statement.

    #![allow(unreachable_code)]

    fn main() {
        'outer: loop {
            println!("Entered the outer loop");

            'inner: loop {
                println!("Entered the inner loop");

                // This would break only the inner loop
                //break;

                // This breaks the outer loop
                break 'outer;
            }

            println!("This point will never be reached");
        }

        println!("Exited the outer loop");
    }
