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: Point

Last known pointer position (client coordinates).

§grab: Point

Where inside the dragged element the user grabbed it.

§effect: DropEffect

Effect requested by the draggable.

§mode: DragMode

How this drag is being driven (pointer vs keyboard).

§pointer_kind: PointerKind

Which 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.
