This rust crate implements a "robust" version of the Bentley-Ottmann sweep-line algorithm, and uses it to provide various two-dimensional geometric primitives like boolean operations on sets bounded by Bézier paths. It is currently in an early beta state.

To compute binary operations between curves, use the binary_op function, which takes in two paths and computes some binary operation on them:

use kurbo::Shape;
use linesweeper::{binary_op, FillRule, BinaryOp};

let square = kurbo::Rect::from_center_size((0.0, 0.0), (2.0, 2.0)).to_path(1e-6);
let circle = kurbo::Circle::new((0.0, 0.0), 1.2).to_path(1e-6);
binary_op(&square, &circle, FillRule::EvenOdd, BinaryOp::Intersection);

For more advanced usage (like custom n-ary operations) see Topology, or the example in examples/bus.rs.
