Expand description
Object to be passed in visit_item_children method of the Component.
Fields
visit_item: unsafe extern "C" fn(_: VRefMut<'_, ItemVisitorVTable>, component: &VRc<ComponentVTable, Dyn>, index: usize, item: Pin<VRef<'_, ItemVTable>>) -> VisitChildrenResult
Called for each children of the visited item
The component
parameter is the component in which the item live which might not be the same
as the parent’s component.
index
is to be used again in the visit_item_children function of the Component (the one passed as parameter)
and item
is a reference to the item itself
drop: unsafe extern "C" fn(_: VRefMut<'_, ItemVisitorVTable>)
Destructor
Implementations
Create a vtable suitable for a given type implementing the trait.
Trait Implementations
type VTable = ItemVisitorVTable
type VTable = ItemVisitorVTable
That’s the VTable itself (so most likely Self)
