Struct geo::Point
[−]
[src]
pub struct Point<T>(pub Coordinate<T>)
where
T: Float;
A single Point in 2D space.
Points can be created using the new(x, y)
constructor, or from a Coordinate
or pair of points.
use geo::{Point, Coordinate}; let p1: Point<f64> = (0., 1.).into(); let c = Coordinate{ x: 10., y: 20.}; let p2: Point<f64> = c.into();
