Error code E0590
break
or continue
keywords were used in a condition of a while
loop
without a label.
Erroneous code code:
#![allow(unused)] fn main() { while break {} }
break
or continue
must include a label when used in the condition of a
while
loop.
To fix this, add a label specifying which loop is being broken out of:
#![allow(unused)] fn main() { 'foo: while break 'foo {} }
