Crate maps_engine_rust 

maps_engine_rust

Zero-dependency map engine core in Rust — a port of the TypeScript maps-engine.

Provides the math every slippy-map needs, without any rendering or DOM:

• projection — Web Mercator lon/lat ↔ pixel math
• tile — XYZ tile ids, bounds, quadkeys
• geo — haversine distance, bearings, destinations
• geofence — polygon & circle geofences
• view — camera state (center, zoom, bearing, pitch)
• cluster — grid marker clustering
• heatmap — heatmap intensity grids
• draw — drawing session with undo/redo
• measure — distance / area measurement + formatting
• navigation — turn-by-turn maneuver detection & progress
• geojson — minimal GeoJSON types

Rendering (canvas/wgpu/web-sys) is intentionally out of scope — pair this crate with your renderer of choice.
