Crate foodshare_geo 

High-performance geospatial utilities for FoodShare.

This crate provides:

• Haversine distance calculations
• PostGIS POINT parsing (JSON and WKT formats)
• Batch processing with optional parallelism
• WASM bindings for browser usage

Example

use foodshare_geo::{haversine_distance, Coordinate};

let coord1 = Coordinate::new(52.5200, 13.4050); // Berlin
let coord2 = Coordinate::new(48.8566, 2.3522);  // Paris

let distance_km = haversine_distance(&coord1, &coord2);
assert!((distance_km - 878.0).abs() < 10.0); // ~878 km
