Struct geohashrust::GeoLocation
[−]
[src]
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
[src]
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);
