Coverage stats for a STEP export.

Fields

total: usize

Entities in the source model.

written: usize

Entities written (after filtering + reference closure).

copies_refused: usize

Copy-on-write mutations the file could not express, so none was made. Non-zero means an edit the caller asked for is not in the output, and the caller is the only one who can say what to do about it.

refused_refs: usize

#<digits> references above u32::MAX refused (issue #3421) while resolving a filtered export’s reference closure. The referenced record could never itself be a real entity, so this excludes nothing reachable — it only says the source has an id ifc-lite can’t hold (#3752).

attribute_edits_refused: usize

Records with a root-attribute edit that could not be applied: the record’s own argument list did not scan into slots, so the line was emitted as the source wrote it (issue #4125), or an edit’s index is past the record’s arity, so that edit was dropped and the others kept. Non-zero means an edit the caller asked for is not in the output. Counted rather than left as an unchanged line, because a refusal that looks like a successful no-op is the failure this whole family is about: writing by index into a mis-scanned list lands on the wrong attribute and reports success.

owner_history_unfilled: usize

Records written to an IFC2X3 downgrade with $ in OwnerHistory, which IFC2X3 requires, because the export writes no IfcOwnerHistory to point it at (#4686). Non-zero means the file is not valid IFC2X3. Records the source gave $ are otherwise pointed at the first owner history the export writes; none is invented.

required_slots_unfilled: usize

SLOTS other than OwnerHistory written to an IFC2X3 export with $ where IFC2X3 requires a value and the schema offers no default that claims nothing (#4714): measures, labels, identifiers, entity references, and enums with no NOTDEFINED member such as IfcBuildingStorey.CompositionType. Non-zero means the file is not valid IFC2X3. Counted per slot, not per record: one record can leave several. Slots whose IFC2X3 declaration DOES offer such a default take .NOTDEFINED. or .F. and are not counted.

ifc4_required_slots_unfilled: usize

SLOTS written to an IFC4X3/IFC5 -> IFC4 downgrade with $ where IFC4 requires a value (#5307, the Rust twin of #5202). The converter never invents one: no measure, label, identifier, reference, flag or enum. Non-zero means the file is not valid IFC4. Counted per slot, not per record. Zero for every other direction, including IFC2X3 -> IFC4.

enum_values_lost: usize

Enum values the target schema does not define that a conversion wrote as .NOTDEFINED. or $, or as .USERDEFINED. without room for the member name (#5365). Non-zero means information was lost.

enum_values_refused: usize

Enum values the target schema does not define and offers no valid replacement for, so they were kept as written (#5365). Non-zero means the file is not valid against its header.
