Struct geohashrust::GeoLocation

pub struct GeoLocation {
    pub latitude: f64,
    pub longitude: f64,
}

A geographic location.

Fields

latitude: f64

Latitude in degrees.

longitude: f64

Longitude in degrees.

Methods

impl GeoLocation

fn new() -> GeoLocation

Creates a new GeoLocation with latitude and longitude set to zero.

Example

let l = geohashrust::GeoLocation::new();
assert_eq!(l.latitude, 0.0);
assert_eq!(l.longitude, 0.0);

fn from_coordinates(latitude: f64, longitude: f64) -> GeoLocation

Creates a new GeoLocation with latitude and longitude.

Example

let l = geohashrust::GeoLocation::from_coordinates(48.1333, 11.5667);
assert_eq!(l.latitude, 48.1333);
assert_eq!(l.longitude, 11.5667);

fn distance_to(&self, other: &GeoLocation) -> f64

Returns the distance between self and other in meters. The calculation is done using the Haversine formula.

Example

let new_york = geohashrust::GeoLocation::from_coordinates(40.7127, -74.0059);
let helsinki = geohashrust::GeoLocation::from_coordinates(60.1708, 24.9375);
assert_eq!(new_york.distance_to(&helsinki).round(), 6618.0);

Trait Implementations

impl Default for GeoLocation

fn default() -> GeoLocation

Returns the "default value" for a type.

impl Clone for GeoLocation

fn clone(&self) -> GeoLocation

Returns a copy of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Copy for GeoLocation

impl PartialEq for GeoLocation

fn eq(&self, __arg_0: &GeoLocation) -> bool

This method tests for self and other values to be equal, and is used by ==.

fn ne(&self, __arg_0: &GeoLocation) -> bool

This method tests for !=.

impl Sub<GeoLocation> for GeoLocation

Returns the distance between self and other in meters. The calculation is done using the Haversine formula.

Example

let new_york = geohashrust::GeoLocation::from_coordinates(40.7127, -74.0059);
let helsinki = geohashrust::GeoLocation::from_coordinates(60.1708, 24.9375);
assert_eq!((new_york-helsinki).round(), 6618.0);

type Output = f64

The resulting type after applying the - operator

fn sub(self, rhs: GeoLocation) -> f64
