Struct rustc_mir_build::build::matches::util::FakeBorrowCollector

source ·
pub(super) struct FakeBorrowCollector<'a, 'b, 'tcx> {
    cx: &'a mut Builder<'b, 'tcx>,
    scrutinee_base: PlaceBase,
    fake_borrows: FxIndexMap<Place<'tcx>, FakeBorrowKind>,
}

Fields§

§cx: &'a mut Builder<'b, 'tcx>§scrutinee_base: PlaceBase

Base of the scrutinee place. Used to distinguish bindings inside the scrutinee place from bindings inside deref patterns.

§fake_borrows: FxIndexMap<Place<'tcx>, FakeBorrowKind>

Store for each place the kind of borrow to take. In case of conflicts, we take the strongest borrow (i.e. Deep > Shallow). Invariant: for any place in fake_borrows, all the prefixes of this place that are dereferences are also borrowed with the same of stronger borrow kind.
