[src]
T: CoordNum,
NT: CoordNum,
Apply a function to all the coordinates in a geometric object, returning a new object.
Examples
use geo::algorithm::map_coords::MapCoords; use geo::Point; 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));
