Enum EditError 

pub enum EditError {
    StaleHandle,
    VerticesNotOnFace,
    DegenerateCut,
    BordersExterior,
    BridgeEdge,
    VertexNotDissolvable,
    InvalidPolygon,
}

Errors an edit op can reject with. Build never fails — a malformed input just yields fewer (or zero) interior faces, matching the TS detector.

Variants

StaleHandle

A referenced id is tombstoned or out of range.

VerticesNotOnFace

split_face: the two vertices aren’t both on the target face.

DegenerateCut

split_face: the two endpoints are the same, or already adjacent on the face (the cut would have zero area on one side).

BordersExterior

merge_faces: the edge borders the exterior, so there’s no second room to merge with (that’s a delete, not a merge).

BridgeEdge

merge_faces: both sides are the same face — the edge is a bridge, and removing it would change connectivity rather than union two rooms.

VertexNotDissolvable

dissolve_vertex: the vertex isn’t a simple degree-2 node (a junction where 3+ walls meet, or a dangling tip), so there’s no unambiguous pair of edges to weld into one.

InvalidPolygon

add_face: the ring has fewer than 3 points, self-intersects, or encloses near-zero area.
