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, unused_labels)] 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"); }
