pub trait Destination<F: CoordFloat> {
// Required method
fn destination(&self, origin: Point<F>, bearing: F, distance: F) -> Point<F>;
}Expand description
Calculate the destination point from an origin point, given a bearing and a distance.
Required Methods§
Sourcefn destination(&self, origin: Point<F>, bearing: F, distance: F) -> Point<F>
fn destination(&self, origin: Point<F>, bearing: F, distance: F) -> Point<F>
Returns a new point having travelled the distance along a line
from the origin point with the given bearing.
See specific implementations for details.
§Units
origin: Point where the units of x/y depend on the trait implementation.bearing: degrees, where: North: 0°, East: 90°, South: 180°, West: 270°distance: depends on the trait implementation.- returns: Point where the units of x/y depend on the trait implementation.
§Examples
use geo::{Haversine, Rhumb, Geodesic, Destination, Point};
let point = Point::new(0.0, 0.0);
assert_relative_eq!(Haversine.destination(point, 45.0, 111_111.0), Point::new(0.706607921147679, 0.7065541919063233));
assert_relative_eq!(Geodesic.destination(point, 45.0, 111_111.0), Point::new(0.7058183774535367, 0.7105205988658333));
assert_relative_eq!(Rhumb.destination(point, 45.0, 111_111.0), Point::new(0.706590011673029, 0.7065721019258285));
