Struct elastic_types::geo::point::GeoPoint
[−]
[src]
pub struct GeoPoint<TMapping> where
TMapping: GeoPointMapping, { /* fields omitted */ }
An Elasticsearch geo_point
type with a format.
The format is provided as a generic parameter.
This struct wraps up a geo::Point
struct, which have an x
and y
floating point value.
Examples
Defining a geo point using the default format:
let point: GeoPoint<DefaultGeoPointMapping> = GeoPoint::build(1.0, 1.0);
Defining a geo point using a named format:
let point: GeoPoint<DefaultGeoPointMapping<GeoPointString>> = GeoPoint::build(1.0, 1.0);
Accessing the values of a geo point:
let point: GeoPoint<DefaultGeoPointMapping> = GeoPoint::build(1.0, 1.0); //eg: (1.0,1.0) println!("({},{})", point.x(), point.y() );

Methods
impl<TMapping> GeoPoint<TMapping> where
TMapping: GeoPointMapping,
[src]
TMapping: GeoPointMapping,
pub fn new<I>(point: I) -> Self where
I: Into<P<f64>>,
[src]
I: Into<P<f64>>,
Creates a new GeoPoint
from the given coordinate.
This function will consume the provided Coordinate
.
Examples
use geo::{ Point, Coordinate }; use elastic_types::prelude::*; //Create a geo Coordinate struct let coord = Coordinate { x: 1.0, y: 1.0 }; //Give it to the GeoPoint struct let point: GeoPoint<DefaultGeoPointMapping> = GeoPoint::new(Point(coord));
pub fn build(x: f64, y: f64) -> Self
[src]
Creates an GeoPoint
from the given x
and y
primitives:
let point: GeoPoint<DefaultGeoPointMapping> = GeoPoint::build(1.0, 1.0);
pub fn remap<TNewMapping>(point: GeoPoint<TMapping>) -> GeoPoint<TNewMapping> where
TNewMapping: GeoPointMapping,
[src]
TNewMapping: GeoPointMapping,
Change the format/mapping of this geo point.
Examples
//Get a point formatted as a string let point: GeoPoint<DefaultGeoPointMapping<GeoPointString>> = GeoPoint::build(1.0, 1.0); //Change the format to an object let otherpoint: GeoPoint<DefaultGeoPointMapping<GeoPointObject>> = GeoPoint::remap(point);
Methods from Deref<Target = P<f64>>
pub fn x(&self) -> T
[src]
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);
pub fn y(&self) -> T
[src]
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);
pub fn lng(&self) -> T
[src]
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);
pub fn lat(&self) -> T
[src]
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);
pub fn dot(&self, point: &Point<T>) -> T
[src]
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);
