Function meshed_representations 

pub fn meshed_representations<'a>(
    element: &'a DecodedEntity,
    representations: &'a [DecodedEntity],
) -> impl Iterator<Item = &'a DecodedEntity> + 'a

The representations of element (its IfcProductDefinitionShape Representations, decoded) that the element meshing paths mesh, in order: each IfcShapeRepresentation whose effective type is body geometry, or an annotation’s 2D fill, or that names no type at all, minus a MappedRepresentation when the element also carries direct body geometry. Anything that must agree with what renders (the IgnoreOpaque opening filter in ifc-lite-processing, #4699) selects through this.
