}Expand description
A snapshot of an in-flight drag.
Deriving Store generates per-field lenses, which
DndContext’s accessors use for granular subscriptions.
Fields§
§payload: Option<T>The payload currently being dragged, if any.
source: Option<ZoneId>Zone the drag started from.
over: Option<ZoneId>Zone the pointer is currently over.
pointer: PointLast known pointer position (client coordinates).
grab: PointWhere inside the dragged element the user grabbed it.
effect: DropEffectEffect requested by the draggable.
mode: DragModeHow this drag is being driven (pointer vs keyboard).
pointer_kind: PointerKindWhich pointer device drives a pointer drag (mouse/touch/pen).
Meaningful only while mode is DragMode::Pointer; host-side
glue reads it to bridge exactly the input layers the device
needs (see PointerKind). Draggable records it at pickup;
custom sources that never do get the safe Mouse default.
source_rect: Option<Rect>Client rect of the dragged element, measured at pickup. Feeds
size-matched ghosts (DragOverlay { match_source: true }); None
until the async measurement lands or when a custom source never set
it.
refocus: Option<T>Payload of a just-completed keyboard drop, awaiting focus
restoration: the drop re-mounts the moved item at its landing place
and the browser dumps focus on <body> when the source element
unmounts, so the matching Draggable claims this on mount and
focuses itself - keyboard users keep their place. Cleared by the
claim or by the next drag starting.
settle: Option<Rect>Destination rect of a just-completed drop whose overlay is still
gliding home (the drop-settle animation). While set, dragging() is
false but payload stays readable so the ghost keeps its content.
