Trait geo::algorithm::closest_point::ClosestPoint [−][src]
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
fn closest_point(&self, p: &Rhs) -> Closest<F>
[src]
Find the closest point between self
and p
.
