Struct rustc_mir::monomorphize::polymorphize::MarkUsedGenericParams

struct MarkUsedGenericParams<'a, 'tcx> {
    tcx: TyCtxt<'tcx>,
    def_id: DefId,
    unused_parameters: &'a mut FiniteBitSet<u32>,
}

Visitor used to aggregate generic parameter uses.

Fields

tcx: TyCtxt<'tcx>

def_id: DefId

unused_parameters: &'a mut FiniteBitSet<u32>

Implementations

impl<'a, 'tcx> MarkUsedGenericParams<'a, 'tcx>

fn visit_child_body(&mut self, def_id: DefId, substs: SubstsRef<'tcx>)

Invoke unused_generic_params on a body contained within the current item (e.g. a closure, generator or constant).
