struct Validator<'a, 'tcx> {
    ccx: &'a ConstCx<'a, 'tcx>,
    temps: &'a mut IndexSlice<Local, TempState>,
}
Expand description

Checks whether locals that appear in a promotion context (Candidate) are actually promotable.

This wraps an Item, and has access to all fields of that Item via Deref coercion.
