ifc-constraint 0.2.1

Bounded IFC4 metric, objective, and constraint relationships.
Documentation

ifc-constraint

Bounded IFC4 constraint semantics: IfcMetric, IfcObjective and their relationships, as borrowed views over ifc-model plus transaction-staged authoring. 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.
