Named breaks in for loops in Rust
Is there a way to have nested for loops in Rust and break the outer one from inside the inner one, the way one could do e.g. in Java? I know Rust supports named breaks in loop but I can't seem to find information about the same regarding for.
Yes. It uses the same syntax as lifetimes.
fn main() {
'outer: for x in 0..5 {
'inner: for y in 0..5 {
println!("{},{}", x, y);
if y == 3 {
break 'outer;
}
}
}
}
See loop labels documentation and the related section of the reference.
