Enum BareTopology 

pub enum BareTopology {
    Loop,
    Vertex,
}

Stage a bare IfcLoop or IfcVertex.

Both are concrete in the schema despite having no attributes, and both are ordinarily written as one of their subtypes – poly_loop, edge_loop, vertex_loop, vertex_point. The bare forms exist for a topology that names a connection without yet describing its geometry, which round-tripping a partial model requires: refusing to write them would make this library unable to reproduce a file it can read.

Variants

Loop

IfcLoop: a closed path with no stated geometry.

Vertex

IfcVertex: a point with no stated geometry.
