Struct ModelMetadata 

pub struct ModelMetadata {
    pub schema_version: String,
    pub entity_count: usize,
    pub geometry_entity_count: usize,
    pub coordinate_info: CoordinateInfo,
    pub length_unit_scale: Option<f64>,
    pub georeferencing: Option<Georeferencing>,
}

Model metadata extracted from the IFC file.

Fields

schema_version: String

IFC schema version (e.g., “IFC2X3”, “IFC4”, “IFC4X3”).

entity_count: usize

Total number of entities in the file.

geometry_entity_count: usize

Number of geometry-bearing entities.

coordinate_info: CoordinateInfo

Coordinate system information.

length_unit_scale: Option<f64>

Length unit scale to convert model length values to metres (e.g. 0.001 for millimetres). None when not yet computed; consumers treat it as 1.0. Brings the server to parity with the browser parser’s extractLengthUnitScale (issue #900).

georeferencing: Option<Georeferencing>

Georeferencing (IfcMapConversion + IfcProjectedCRS). None when the model carries no map-conversion data. Mirrors the browser parser’s extractGeoreferencing (issue #900).
