Struct svc_scheduler_client_grpc::prelude::scheduler_storage::vertipad::Point

pub struct Point<T = f64>(pub Coord<T>)
where
    T: CoordNum;

A single point in 2D space.

Points can be created using the Point::new constructor, the [point!] macro, or from a Coord, two-element tuples, or arrays – see the From impl section for a complete list.

Semantics

The interior of the point is itself (a singleton set), and its boundary is empty. A point is valid if and only if the Coord is valid.

Examples

use geo_types::{coord, Point};
let p1: Point = (0., 1.).into();
let c = coord! { x: 10., y: 20. };
let p2: Point = c.into();

Tuple Fields

0: Coord<T>

Note on Robustness

This function is not robust against floating-point errors. The geo crate offers robust predicates for standard numeric types using the Kernel trait, and these should be preferred if possible.

Examples

use geo_types::point;

let point_a = point! { x: 1., y: 2. };
let point_b = point! { x: 3., y: 5. };
let point_c = point! { x: 7., y: 12. };

assert_eq!(x.round(), 71.0);
assert_eq!(y.round(), 134.0);

pub fn to_radians(self) -> Point<T>

Example

let (x, y): (f32, f32) = p.to_radians().x_y();
assert_eq!(x.round(), 3.0);
