Crate ifc_constraint

Expand description

Bounded IFC4 metric, objective, and constraint-relationship semantics.

Values are projected and preserved; this crate does not evaluate compliance, formulas, references, tables, or time series.

Structs§

ConstraintAssignment: Strict borrowed IFC4 projection.
ConstraintAssociationDraft: Draft for one rooted constraint association.
ConstraintBaseDraft: Common inherited IfcConstraint fields.
ConstraintView: Borrowed entry point for constraint projections and inverse-style queries.
Metric: Strict borrowed IFC4 projection.
MetricDraft: Draft for one IfcMetric.
Objective: Strict borrowed IFC4 projection.
ObjectiveDraft: Draft for one IfcObjective.
ReferenceDraft: Draft for one IfcReference: a path into another entity’s attributes.
ResourceConstraintDraft: Draft for one resource-level constraint relationship.
ResourceConstraintRelationship: Strict borrowed IFC4 projection.

Benchmark: Comparison operator carried by IfcMetric.
ConstraintError: Constraint projection or authoring failure.
ConstraintGrade: Severity/handling grade of an IFC constraint.
LogicalOperator: Logical aggregation operator carried by IfcObjective.
MetricValue: Preserved IfcMetricValueSelect without evaluating its meaning.
MetricValueDraft: Authoring form of a preserved IfcMetricValueSelect.

associate_constraint: Validate and stage one rooted constraint association.
associate_constraint_with_owner_history: associate_constraint with a caller-supplied IfcOwnerHistory, which IFC2X3 requires on every IfcRoot.
create_metric: Validate and stage one metric.
create_objective: Validate and stage one objective.
create_reference: Stage an IfcReference.
relate_resource_constraint: Validate and stage one resource-level constraint relationship.
