Methods

impl Point

fn new(x: f64, y: f64) -> Point

Creates a new point.

use geo::Point;

let p = Point::new(1.234, 2.345);

assert_eq!(p.x(), 1.234);
assert_eq!(p.y(), 2.345);

fn x(&self) -> f64

Returns the x/horizontal component of the point.

use geo::Point;

let p = Point::new(1.234, 2.345);

assert_eq!(p.x(), 1.234);

fn set_x(&mut self, x: f64) -> &mut Point

Sets the x/horizontal component of the point.

use geo::Point;

let mut p = Point::new(1.234, 2.345);
p.set_x(9.876);

assert_eq!(p.x(), 9.876);

fn y(&self) -> f64

Returns the y/vertical component of the point.

use geo::Point;

let p = Point::new(1.234, 2.345);

assert_eq!(p.y(), 2.345);

fn set_y(&mut self, y: f64) -> &mut Point

Sets the y/vertical component of the point.

use geo::Point;

let mut p = Point::new(1.234, 2.345);
p.set_y(9.876);

assert_eq!(p.y(), 9.876);

fn lng(&self) -> f64

Returns the longitude/horizontal component of the point.

use geo::Point;

let p = Point::new(1.234, 2.345);

assert_eq!(p.lng(), 1.234);

fn set_lng(&mut self, lng: f64) -> &mut Point

Sets the longitude/horizontal component of the point.

use geo::Point;

let mut p = Point::new(1.234, 2.345);
p.set_lng(9.876);

assert_eq!(p.lng(), 9.876);

fn lat(&self) -> f64

Returns the latitude/vertical component of the point.

use geo::Point;

let p = Point::new(1.234, 2.345);

assert_eq!(p.lat(), 2.345);

fn set_lat(&mut self, lat: f64) -> &mut Point

Sets the latitude/vertical component of the point.

use geo::Point;

let mut p = Point::new(1.234, 2.345);
p.set_lat(9.876);

assert_eq!(p.lat(), 9.876);

fn dot(&self, point: &Point) -> f64

Returns the dot product of the two points: dot = x1 * x2 + y1 * y2

use geo::Point;

let p = Point::new(1.5, 0.5);
let dot = p.dot(&Point::new(2.0, 4.5));

assert_eq!(dot, 5.25);
