Crate klayout_geom 

klayout-geom — geometric algorithms over klayout-core types.

Region is the central abstraction: a deterministic, merged set of polygons on a single conceptual layer. Boolean ops and sizing produce Regions; flattening a hierarchical (Library, CellId, LayerIndex) into a Region is the bridge to verification and routing.

Modules

boolean

Boolean ops on Regions, backed by i_overlay.

convex

Convex decomposition of polygons via ear-clipping.

edges

Edge collections — first-class edges as a complement to Region.

fracture

Mask-data fracturing — trapezoidalisation.

path

Path → Polygon rendering.

region

Region — a deterministic, normalized set of polygons on a single layer.

select

Selection / classification operators on Region — the core KLayout deck DSL primitives.

simplify

Polygon vertex-reduction via Douglas-Peucker.

size

Sizing (offset / Minkowski sum with a disk-equivalent).
