Crate polyops 

PolyOps

Boolean operations on polygons via the Martinez-Rueda-Feito sweep-line algorithm. Faithful Rust port of martinez-polygon-clipping.

Operations

• intersection — the area covered by both subject and clipping.
• union — the area covered by either subject or clipping.
• difference — the area in subject but not in clipping.
• xor — the area in subject xor clipping (symmetric difference).

All four accept GeoJSON-shaped coordinate arrays: either a Polygon (Vec<Ring>) or a MultiPolygon (Vec<Polygon>), via the Geometry enum.

Status

Pre-alpha. All algorithm modules are ported; parity against upstream is verified via tests/parity.rs against goldens generated by parity/generate-goldens.ts. Failure modes (if any) get tracked in PLAN.md §14.
