Crate tg_geom 

Rust bindings for the TG Geometry library.

TG is a fast and lightweight geometry library for C that provides spatial operations including point-in-polygon, intersection tests, and more.

Quick Start

use tg_geom::{Geom, GeomType, Point, init_mimalloc};

// Initialize mimalloc allocator (requires `mimalloc` feature)
init_mimalloc();

// Create a point geometry
let point = Geom::new_point(Point::new(1.0, 2.0)).unwrap();
assert_eq!(point.geom_type(), GeomType::Point);

// Parse from WKT
let polygon = Geom::from_wkt("POLYGON((0 0, 10 0, 10 10, 0 10, 0 0))").unwrap();

// Spatial predicates
let test_point = Geom::new_point(Point::new(5.0, 5.0)).unwrap();
assert!(polygon.contains(&test_point));

// Export to different formats
let geojson = polygon.to_geojson();
let wkb = polygon.to_wkb();

Features

• mimalloc - Use mimalloc as the memory allocator (recommended for performance)
