Enum MeshClosure 

#[non_exhaustive]
pub enum MeshClosure {
    Solid,
    Surface,
    Unknown,
    OpenSolid,
}

Whether a compiled mesh bounds a solid (#161).

A triangle mesh looks the same either way: a closed surface model (say, an IFC IfcShellBasedSurfaceModel shaped like a box) is watertight, so its divergence sum is a finite, plausible number. It is still not a volume, because the source never claimed one. This is what tells the two apart.

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.

Solid

Every part of the mesh is the boundary of a solid; its enclosed volume is meaningful.

Surface

At least one part is a surface with no solid behind it: an open shell, a face or a trimmed surface patch (#311), or a closed shell the source never declared a solid. Area is meaningful; volume is not.

Unknown

The compiler did not report it.

OpenSolid

The source declared a solid, but the compiled mesh is not closed: some edge is not shared by exactly two triangles running it in opposite directions (#265). Neither its volume nor its closure can be trusted; the compiler reports this rather than claiming a solid for a mesh with boundary edges.
