struct PossibleBorrowerVisitor<'a, 'b, 'tcx> {
possible_borrower: TransitiveRelation,
body: &'b Body<'tcx>,
cx: &'a LateContext<'tcx>,
possible_origin: FxHashMap<Local, HybridBitSet<Local>>,
}Expand description
Collects the possible borrowers of each local.
For example, b = &a; c = &a; will make b and (transitively) c
possible borrowers of a.
