Required methods
fn map_coords(&self, func: &dyn Fn(&(T, T)) -> (NT, NT)) -> Self::Output where
T: CoordinateType,
NT: CoordinateType,
T: CoordinateType,
NT: CoordinateType,
Apply a function to all the coordinates in a geometric object, returning a new object.
Examples
use geo::Point; use geo::algorithm::map_coords::MapCoords; let p1 = Point::new(10., 20.); let p2 = p1.map_coords(&|&(x, y)| (x+1000., y*2.)); assert_eq!(p2, Point::new(1010., 40.));
You can convert the coordinate type this way as well
let p1: Point<f32> = Point::new(10.0f32, 20.0f32); let p2: Point<f64> = p1.map_coords(&|&(x, y)| (x as f64, y as f64)); assert_eq!(p2, Point::new(10.0f64, 20.0f64));
