Module geometry 

GeoJSON-compatible geometry types.

Supports Point, LineString, Polygon, MultiPoint, MultiLineString, MultiPolygon, and GeometryCollection. Stored as GeoJSON for JSON compatibility. Includes distance (Haversine), area, bearing, and centroid calculations.

Structs

Coord

A 2D coordinate (longitude, latitude) following GeoJSON convention. Note: GeoJSON uses [lng, lat] order, NOT [lat, lng].

Enums
