Documentation on docs.rs

Crate on crates.io

A tiny Rust library for finding the intersection of two lines, rays, or line segments.

extern crate geo;
extern crate line_intersection;

fn main() {
    // find the intersection of a line segment and an infinite line
    use line_intersection::{LineInterval, LineRelation};
    use geo::{Coordinate, Line, Point};

    let segment = LineInterval::line_segment(Line {
        start: (0.0, 0.0).into(),
        end: (3.0, 3.0).into(),
    });

    let line = LineInterval::line(Line {
        start: (2.0, 0.0).into(),
        end: (2.0, 0.1).into(),
    });

    let intersection = segment.relate(&line).unique_intersection();
    assert_eq!(Some(Point(Coordinate { x: 2.0, y: 2.0 })), intersection);
}
