pub trait ItemVisitor {
    // Required method
    fn visit_item(
        &mut self,
        _1: &VRc<ItemTreeVTable, Dyn>,
        _2: u32,
        _3: Pin<VRef<'_, ItemVTable>>,
    ) -> VisitChildrenResult;
}

fn visit_item( &mut self, _1: &VRc<ItemTreeVTable, Dyn>, _2: u32, _3: Pin<VRef<'_, ItemVTable>>, ) -> VisitChildrenResult
