Node instance.

Fields

kind: NodeKindKey

Node kind identifier.

kind_version: u32

Node kind version (for per-kind migrations).

pos: CanvasPoint

Top-left position in canvas space.

origin: Option<NodeOrigin>

Optional node origin override (XyFlow node.origin).

When omitted, runtime uses the global NodeGraphInteractionState.node_origin.

selectable: Option<bool>

Whether the node can be selected (XyFlow node.selectable).

When omitted, the global NodeGraphInteractionState.elements_selectable decides.

focusable: Option<bool>

Whether the node can receive keyboard focus (XyFlow node.focusable).

When omitted, the global NodeGraphInteractionState.nodes_focusable decides.

draggable: Option<bool>

Whether the node can be dragged with pointer interactions (XyFlow node.draggable).

When omitted, the global NodeGraphInteractionState.nodes_draggable decides.

connectable: Option<bool>

Whether the node can be used for creating connections via editor interactions (XyFlow node.connectable).

When omitted, the global NodeGraphInteractionState.nodes_connectable decides.

deletable: Option<bool>

Whether the node can be deleted via editor interactions (XyFlow node.deletable).

When omitted, the global NodeGraphInteractionState.nodes_deletable decides.

parent: Option<GroupId>

Optional group container id (subflow / parent frame).

This is an editor-structure concept (XyFlow parentId mental model) and is intentionally orthogonal to semantic subgraphs (see ADR 0126).

extent: Option<NodeExtent>

Optional per-node movement/resize extent override.

This mirrors XyFlow’s node.extent concept. It is an editor-structure constraint (UI-facing), not a semantic graph rule.

expand_parent: Option<bool>

Whether moving/resizing this node can expand its parent container (if any).

This mirrors XyFlow’s node.expandParent behavior.

size: Option<CanvasSize>

Optional explicit node size in logical px at zoom=1 (semantic sizing).

The editor converts this into canvas space by dividing by the current zoom so node content remains readable under semantic zoom.

When None, the editor derives the size from measured geometry or style defaults.

hidden: bool

Whether the node is hidden (XyFlow node.hidden).

Hidden nodes are excluded from derived geometry (hit-testing, rendering, fit-view).

collapsed: bool

Whether the node is collapsed.

ports: Vec<PortId>

Stable port ordering for this node (UI-facing).

data: Value

Opaque node payload (domain-owned).

This must be preserved for unknown node kinds.
