Function distance_2d 

Source 
pub fn distance_2d(left: Point2, right: Point2) -> f64
Expand description

Returns the Euclidean distance between two 2D points.

ยงExamples

use use_geometry::{Point2, distance_2d};

let left = Point2::new(0.0, 0.0);
let right = Point2::new(3.0, 4.0);

assert_eq!(distance_2d(left, right), 5.0);
