ifc-constraint 0.3.0

Bounded IFC4 metric, objective, and constraint relationships.
Documentation

ifc-constraint

Bounded constraint semantics: IfcMetric, IfcObjective and their relationships, as borrowed views over ifc-model plus transaction-staged authoring, read and written by attribute name in the model's declared release (IFC2X3, IFC4 or IFC4X3). Values are preserved as authored; the crate does not evaluate compliance or formulas.

cargo add ifc-constraint

The openbim-ifc facade also provides it behind its constraint feature.
