Struct ProvenanceMap 

pub struct ProvenanceMap { /* private fields */ }

Source IFC entities for nodes in one lowered geometry graph.

The map is partial: caller-synthesized nodes created outside an active IFC entity scope have no source instead of receiving a fabricated entity id.

Implementations

impl ProvenanceMap

pub fn source(&self, node: NodeId) -> Option<EntityId>

Return the IFC entity that emitted node, if it has an IFC source.

pub fn len(&self) -> usize

Number of attributed graph nodes.

pub fn is_empty(&self) -> bool

Whether no graph nodes carry IFC attribution.

pub fn iter(&self) -> impl Iterator<Item = (NodeId, EntityId)> + '_

Iterate deterministically over (node, source entity) pairs.
