Enum ExactSource 

#[non_exhaustive]
pub enum ExactSource {
    Occurrence,
    Type(EntityId),
    Material(EntityId),
}

Provenance of an exact result.

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.

Occurrence

Resolved from a property set assigned directly to the occurrence via IfcRelDefinesByProperties.

Type(EntityId)

Resolved from a set in HasPropertySets of the IfcTypeObject with this entity id: inherited through the occurrence’s type, or, when a type object is queried, that object’s own set (#193), so the id is then the queried object’s.

Material(EntityId)

Resolved from a material property set of the material definition with this entity id (#218): an IfcMaterialProperties, or in IFC2X3 one of its subtypes, whose Material is that definition.
