Module metadata 

Entity metadata extraction.

Constants

UNKNOWN_TYPE_FALLBACK 🔒

Unknown-type fallback, mirroring the WASM path’s extractRootAttributesFromEntity: GlobalId 0, Name 2, Description 3, ObjectType 4, Tag 7 (the IfcElement/IfcRoot layout), and NO PredefinedType. Applied only when the type is absent from the schema registry — a KNOWN type without an attribute keeps its -1 and stays empty on both parse paths (issue #3949 extended this fallback to GlobalId/Name).

Functions

enum_at 🔒

PredefinedType enum token at a registry index. STEP enums decode to AttributeValue::Enum with the dots already stripped (.SOLIDWALL. → SOLIDWALL), matching the WASM extractAllEntityAttributes display value — read via as_enum(), never get_string().

extract_entity_metadata 🔒

Extract entity metadata for all entities.

string_at 🔒

Non-empty string attribute at a registry index (-1 = not declared).
