Enum CoordRefSystem 

#[non_exhaustive]
pub enum CoordRefSystem {
    Wgs84,
}

The reference system of the provided coordinates.

Currently only the WGS-84 coordinate reference system is supported. It defines the latitude and longitude of the GeoUri to be in decimal degrees and the altitude in meters.

For more details see the component description in RFC 5870.

Variants (Non-exhaustive)

Non-exhaustive enums could have additional variants added in future. Therefore, when matching against variants of non-exhaustive enums, an extra wildcard arm must be added to account for any future variants.

Wgs84

The WGS-84 coordinate reference system.

Implementations

impl CoordRefSystem

pub fn validate(&self, latitude: f64, longitude: f64) -> Result<(), Error>

Validates geolocation coordinates against the selected coordinate reference system.

Examples

let crs = CoordRefSystem::Wgs84;
assert_eq!(crs.validate(52.107, 5.134), Ok(()));
assert_eq!(
    crs.validate(100.0, 5.134), // Latitude not in range `-90.0..=90.0`!
    Err(Error::OutOfRangeLatitude)
);
assert_eq!(
    crs.validate(51.107, -200.0), // Longitude not in range `-180.0..=180.0`!
    Err(Error::OutOfRangeLongitude)
);

Errors

An error is returned if the latitude/longitude is out of range with respect to the coordinate reference system.

Trait Implementations

impl Clone for CoordRefSystem

fn clone(&self) -> CoordRefSystem

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Copy for CoordRefSystem

impl Debug for CoordRefSystem

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Default for CoordRefSystem

fn default() -> Self

Returns the “default value” for a type.

impl Eq for CoordRefSystem

impl PartialEq for CoordRefSystem

fn eq(&self, other: &CoordRefSystem) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
