Struct ExportModel 

pub struct ExportModel {
    pub entities: Vec<EntityRow>,
    pub units: UnitScales,
}

The full extracted model.

Fields

entities: Vec<EntityRow>

units: UnitScales

The model’s unit scales, resolved from its IFCPROJECT.

Every value EntityRow carries is in the file’s OWN units: the properties, the quantities, and the schema-declared attributes alike. A millimetre model yields a Qto_WallBaseQuantities.Length (a quantity) of 3000, not 3, and an IfcReinforcingBar.NominalDiameter (an attribute) of 29, not 0.029. The geometry exporters normalise to metres; this path deliberately does not, because a property value is not always a length and coercing one would be guessing. That leaves the caller needing the scale to interpret anything dimensional, and until now it had no way to obtain it: the resolver was internal and ExportModel carried only entities. A consumer writing quantities alongside exported geometry therefore had a silent 1000x mismatch with no value on hand to detect it with.

Trait Implementations

impl Clone for ExportModel

fn clone(&self) -> ExportModel

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for ExportModel

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl PartialEq for ExportModel

fn eq(&self, other: &ExportModel) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
