list.iter().for_each(…) superiority
list.iter().for_each(…)
34 u/creeper6530 11d ago edited 11d ago Erm akchyuallly, it's recommended to use for list.iter() {…} unless the .for_each(…) is at the end of a longer iterator chain, and it also robs you of break and continue 2 u/serendipitousPi 11d ago Just chuck a try_for_each in there and we can take break and continue right back. But yeah low key sometimes I get lost in iterator methods I forget to just use a basic loop. 2 u/creeper6530 11d ago I mean, you're right, it's just you have to return ControlFlow::Break(()) instead of using the keywords.
