pub trait ClosestPoint<F: GeoFloat, Rhs = Point<F>> {
// Required method
fn closest_point(&self, p: &Rhs) -> Closest<F>;
}Expand description
Find the closest Point between a given geometry and an input Point.
The closest point may intersect the geometry, be a single
point, or be indeterminate, as indicated by the value of the returned enum.
§Examples
We have a horizontal line which goes through (-50, 0) -> (50, 0),
and want to find the closest point to the point (0, 100).
Drawn on paper, the point on the line which is closest to (0, 100) is the origin (0, 0).
let p: Point<f32> = Point::new(0.0, 100.0);
let horizontal_line: Line<f32> = Line::new(Point::new(-50.0, 0.0), Point::new(50.0, 0.0));
let closest = horizontal_line.closest_point(&p);
assert_eq!(closest, Closest::SinglePoint(Point::new(0.0, 0.0)));Required Methods§
Sourcefn closest_point(&self, p: &Rhs) -> Closest<F>
fn closest_point(&self, p: &Rhs) -> Closest<F>
Find the closest point between self and p.
