LL | while false {
| ^^^^^^^^^^^ this might have zero elements to iterate on
LL | return
| ------ if the loop doesn't execute, this value would never get returned
= help: return a value for the case when the loop has zero elements to iterate on, or consider changing the return type to account for that possibility
error: aborting due to 3 previous errors
