A Component is representing an unit that is allocated together Note: Was generated from the #[vtable] macro on ComponentVTable

Required methods

fn visit_children_item(
    self: Pin<&Self>,
    _1: isize,
    _2: TraversalOrder,
    _3: VRefMut<'_, ItemVisitorVTable>
) -> VisitChildrenResult

Visit the children of the item at index index. Note that the root item is at index 0, so passing 0 would visit the item under root (the children of root). If you want to visit the root item, you need to pass -1 as an index.

fn get_item_ref(self: Pin<&Self>, _1: usize) -> Pin<VRef<'_, ItemVTable>>

Return a reference to an item using the given index

fn parent_item(self: Pin<&Self>, _1: usize, _2: &mut ItemWeak)

Return the parent item. The return value is an item weak because it can be null if there is no parent. And the return value is passed by &mut because ItemWeak has a destructor

fn layout_info(self: Pin<&Self>, _1: Orientation) -> LayoutInfo

Returns the layout info for this component
