Function openrailwaymap_exporter::algorithms::closest_point_in_linestring

pub fn closest_point_in_linestring(
    position: Coord<f64>,
    linestring: &LineString<f64>
) -> Coord<f64>

Returns the closest point of points in a given LineString to a given Coord.

Examples

use geo::{line_string, coord};
use openrailwaymap_exporter::algorithms::closest_point_in_linestring;

let linestring = line_string![
    coord! { x: 0.0, y: 0.0 },
    coord! { x: 0.0, y: 10.0 },
    coord! { x: 50.0, y: 50.0 },
    coord! { x: 100.0, y: 100.0 },
];
let position = coord! { x: 10.0, y: 20.0 };
let closest_position = closest_point_in_linestring(position, &linestring);

assert_eq!(closest_position, coord! { x: 0.0, y: 10.0 });
