pub struct ActiveDrag(pub Option<ActiveDragData>);Expand description
In-flight in-app drag session: the source entity, the payload it
published at drag-start, and the effects it advertises. None when no
drag gesture is active.
Holds the payload for the whole gesture the way a platform session
(NSDraggingSession / IDataObject behind DoDragDrop) owns the
dragged data - so the drop can deliver it even though the source
component may have changed underneath a reactive <for> rebuild.
