Struct ClassificationView 

pub struct ClassificationView<'m> { /* private fields */ }

Entry point for classification/document/library queries over a borrowed Model.

Every projection the view hands out reads against the release the model’s header declares (see crate::classification_schema).

Implementations

impl<'m> ClassificationView<'m>

pub fn classification_assignments( self, ) -> impl Iterator<Item = ClassificationAssignment<'m>> + 'm

All IfcRelAssociatesClassification instances in the model.

pub fn classification_assignments_for( self, object: EntityId, ) -> ClassificationResult<Vec<ClassificationAssignment<'m>>>

Classification assignments naming object among their RelatedObjects, with the relating classification checked against IfcClassificationSelect; fails if object is unknown or a reference does not resolve.

impl<'m> ClassificationView<'m>

pub fn document_assignments( self, ) -> impl Iterator<Item = DocumentAssignment<'m>> + 'm

All IfcRelAssociatesDocument instances in the model.

pub fn document_assignments_for( self, object: EntityId, ) -> ClassificationResult<Vec<DocumentAssignment<'m>>>

Document assignments naming object among their RelatedObjects, with the relating document checked against IfcDocumentSelect; fails if object is unknown or a reference does not resolve.

impl<'m> ClassificationView<'m>

pub fn library_assignments( self, ) -> impl Iterator<Item = LibraryAssignment<'m>> + 'm

All IfcRelAssociatesLibrary instances in the model.

pub fn library_assignments_for( self, object: EntityId, ) -> ClassificationResult<Vec<LibraryAssignment<'m>>>

Library assignments naming object among their RelatedObjects, with the relating library checked against IfcLibrarySelect; fails if object is unknown or a reference does not resolve.

impl<'m> ClassificationView<'m>

pub fn notations(self) -> impl Iterator<Item = ClassificationNotation<'m>> + 'm

All IfcClassificationNotation instances in the model (IFC2X3 only).

pub fn notation( self, id: EntityId, ) -> ClassificationResult<ClassificationNotation<'m>>

Strictly project the IfcClassificationNotation id.

Errors

UnknownEntity, WrongEntityType, or NotInSchema when the bound release (IFC4) does not define notations.

pub fn notation_values(self, id: EntityId) -> ClassificationResult<Vec<&'m str>>

The notation’s code: each facet’s NotationValue, in file order.

Errors

Those of Self::notation, plus a dangling facet, a facet that is not an IfcClassificationNotationFacet, or a facet without a value.

impl<'m> ClassificationView<'m>

pub fn references( self, ) -> impl Iterator<Item = ClassificationReference<'m>> + 'm

All IfcClassificationReference instances in the model.

impl<'m> ClassificationView<'m>

pub fn systems(self) -> impl Iterator<Item = ClassificationSystem<'m>> + 'm

All IfcClassification instances in the model.

impl<'m> ClassificationView<'m>

pub fn documents(self) -> impl Iterator<Item = DocumentInformation<'m>> + 'm

All IfcDocumentInformation instances in the model.

impl<'m> ClassificationView<'m>

pub fn document_references( self, ) -> impl Iterator<Item = DocumentReference<'m>> + 'm

All IfcDocumentReference instances in the model.

impl<'m> ClassificationView<'m>

pub fn external_reference_relationship( self, id: EntityId, ) -> ClassificationResult<ExternalReferenceRelationship<'m>>

Strictly project one generic external-reference relationship.

pub fn external_reference_relationships( self, ) -> impl Iterator<Item = ExternalReferenceRelationship<'m>> + 'm

All generic external-reference relationships in deterministic model order.

pub fn external_references_for( self, resource: EntityId, ) -> ClassificationResult<Vec<ExternalReferenceRelationship<'m>>>

Valid external-reference relationships naming a particular resource.

impl<'m> ClassificationView<'m>

pub fn libraries(self) -> impl Iterator<Item = LibraryInformation<'m>> + 'm

All IfcLibraryInformation instances in the model.

impl<'m> ClassificationView<'m>

pub fn library_references( self, ) -> impl Iterator<Item = LibraryReference<'m>> + 'm

All IfcLibraryReference instances in the model.

impl<'m> ClassificationView<'m>

pub fn hierarchy_from( self, leaf: EntityId, budget: Budget, ) -> ClassificationResult<ClassificationHierarchy<'m>>

Walk ReferencedSource links from leaf up to its root, stopping at the enclosing IfcClassification if present; fails on a cycle, a dangling or mistyped source, or if the walk exceeds budget.

Every distinct entity resolved counts against budget.max_nodes, including the final IfcClassification, and every ReferencedSource edge followed against budget.max_depth. Reaching an entity already on the path is reported as ClassificationError::Cycle, never as a budget error.

pub fn children_of( self, source: EntityId, ) -> ClassificationResult<Vec<ClassificationReference<'m>>>

IfcClassificationReference instances whose ReferencedSource is source, sorted by id; fails if source is unknown or is not itself a classification or reference.

pub fn effective_classifications( self, object: EntityId, ) -> ClassificationResult<EffectiveClassifications<'m>>

Direct classification assignments on object, plus any inherited from its unambiguous IfcRelDefinesByType type; fails if object is unknown, has an assignment with an invalid relating classification, or is related to more than one type.

impl<'m> ClassificationView<'m>

pub const fn new(model: &'m Model) -> Self

Borrow model for classification-schema queries.
