Enum LightSourceKind 

#[non_exhaustive]
pub enum LightSourceKind {
    Ambient,
    Directional,
    Goniometric,
    Positional,
    Spot,
}

Which concrete IfcLightSource subtype an entity declares.

Resolution walks the schema’s inheritance graph, so a subtype introduced by a later schema resolves to its nearest known ancestor rather than being mistaken for an unrelated family. Spot is checked before Positional because IfcLightSourceSpot is a IfcLightSourcePositional.

Variants (Non-exhaustive)

Non-exhaustive enums could have additional variants added in future. Therefore, when matching against variants of non-exhaustive enums, an extra wildcard arm must be added to account for any future variants.

Ambient

IfcLightSourceAmbient: non-directional fill light.

Directional

IfcLightSourceDirectional: parallel rays, no position.

Goniometric

IfcLightSourceGoniometric: photometric light with a distribution curve.

Positional

IfcLightSourcePositional: point light with distance attenuation.

Spot

IfcLightSourceSpot: positional light narrowed to a cone.
