Struct NodeInternalsController 

pub struct NodeInternalsController<'a> { /* private fields */ }

Adapter-facing facade for node-internal geometry lifecycle updates.

This is the headless equivalent of toolkits such as React Flow asking users to update node internals after handles or child widgets move. It keeps the runtime contract explicit while avoiding duplicated adapter code for “mark dirty, report real geometry, query status”.

Implementations

impl<'a> NodeInternalsController<'a>

pub fn invalidate( &mut self, invalidation: NodeInternalsInvalidation, ) -> NodeMeasurementOutcome

Marks one or more node internals dirty until the adapter reports fresh geometry.

pub fn invalidate_one( &mut self, node: NodeId, reason: NodeInternalsInvalidationReason, ) -> NodeMeasurementOutcome

Marks a single node dirty until the adapter reports fresh geometry.

pub fn report( &mut self, measurement: NodeMeasurement, ) -> Result<NodeMeasurementOutcome, NodeMeasurementError>

Reports freshly measured node internals from adapter widget/layout geometry.

pub fn status(&self, node: NodeId) -> NodeMeasurementStatus

Returns whether the latest geometry facts are fresh, dirty, or missing.

pub fn resolve_handle( &self, handle: ConnectionHandleRef, ) -> NodeHandleMeasurementResolution

Resolves local handle geometry from the latest fresh measurement facts.

pub fn layout_facts(&self, viewport_size: CanvasSize) -> LayoutFactsQueryResult

Reads the adapter-facing layout facts after dirty/fresh state has been applied.
