Function difference_polygon_pooled 

pub fn difference_polygon_pooled(
    subject: &Polygon,
    clip: &Polygon,
) -> Result<PoolGuard<'static, Polygon>>

Computes difference of two polygons using object pooling

This is the pooled version of difference_polygon that reuses allocated polygons from a thread-local pool. Returns the first result polygon.

Arguments

• subject - Polygon to subtract from
• clip - Polygon to subtract

Returns

A pooled polygon guard representing the difference (first result if multiple)

Errors

Returns error if polygons are invalid

Example

use oxigdal_algorithms::vector::{difference_polygon_pooled, Coordinate, LineString, Polygon};

let coords1 = vec![
    Coordinate::new_2d(0.0, 0.0),
    Coordinate::new_2d(10.0, 0.0),
    Coordinate::new_2d(10.0, 10.0),
    Coordinate::new_2d(0.0, 10.0),
    Coordinate::new_2d(0.0, 0.0),
];
let ext1 = LineString::new(coords1)?;
let poly1 = Polygon::new(ext1, vec![])?;
let result = difference_polygon_pooled(&poly1, &poly2)?;
