Struct geo::Point

pub struct Point<T>(pub Coordinate<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 Coordinate, 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 Coordinate is valid.

Examples

use geo_types::{Coordinate, Point};
let p1: Point<f64> = (0., 1.).into();
let c = Coordinate { x: 10., y: 20. };
let p2: Point<f64> = c.into();

Tuple Fields

0: Coordinate<T>

pub fn sub(self, rhs: Point<T>) -> Point<T>

Subtract a point from the given point.

Examples

use geo_types::Point;

let p = Point::new(1.25, 3.0) - Point::new(1.5, 2.5);

assert_eq!(p.x(), -0.25);
assert_eq!(p.y(), 0.5);

type Output = Point<T>

The resulting type after applying the - operator.

impl<T> TryFrom<Geometry<T>> for Point<T> where
    T: CoordNum, 

Convert a Geometry enum into its inner type.

Fails if the enum case does not match the type you are trying to convert it to.

type Error = Error

The type returned in the event of a conversion error.

pub fn try_from(
    geom: Geometry<T>
) -> Result<Point<T>, <Point<T> as TryFrom<Geometry<T>>>::Error>

Performs the conversion.

impl<T: CoordNum, NT: CoordNum> TryMapCoords<T, NT> for Point<T>

type Output = Point<NT>

fn try_map_coords(
    &self,
    func: impl Fn(&(T, T)) -> Result<(NT, NT), Box<dyn Error + Send + Sync>>
) -> Result<Self::Output, Box<dyn Error + Send + Sync>>

Map a fallible function over all the coordinates in a geometry, returning a Result

impl<T> VincentyDistance<T, Point<T>> for Point<T> where
    T: CoordFloat + FromPrimitive, 

fn vincenty_distance(&self, rhs: &Point<T>) -> Result<T, FailedToConvergeError>

Determine the distance between two geometries using Vincenty’s formulae.
