Struct GeoLocation

pub struct GeoLocation { /* private fields */ }

A data structure containing a single physical geo-location.

Implementations

impl GeoLocation

pub fn latitude(self) -> f32

Get the latitude.

Examples

let geo = GeoLocation::new(12.345, -98.765)?;
assert_eq!(12.345, geo.latitude());

pub fn longitude(self) -> f32

Get the longitude

Examples

let geo = GeoLocation::new(12.345, -98.765)?;
assert_eq!(-98.765, geo.longitude());

pub fn new(latitude: f32, longitude: f32) -> Result<Self, String>

Create a new GeoLocation.

Errors

Returns Err(String) if either latitude or longitude is not a valid floating-point number, or when they together do not represent a valid geo-location position.

Error Examples

assert_eq!(
    Err("Infinity is not a supported value for longitude".into()),
    GeoLocation::new(23.456, std::f32::NEG_INFINITY)
);

assert_eq!(
    Err("invalid latitude: 123.456 (must be between -90 and 90)".into()),
    GeoLocation::new(123.456, 987.654)
);

Examples

let geo = GeoLocation::new(12.345, -98.765)?;
assert_eq!(12.345, geo.latitude());
assert_eq!(-98.765, geo.longitude());

Trait Implementations

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 Debug for GeoLocation

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

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for GeoLocation

fn deserialize<__D>(__deserializer: __D) -> Result<Self, __D::Error>

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl Display for GeoLocation

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

Formats the value using the given formatter.

impl Hash for GeoLocation

fn hash<__H: Hasher>(&self, state: &mut __H)

Feeds this value into the given Hasher.

fn hash_slice<H>(data: &[Self], state: &mut H)

where H: Hasher, Self: Sized,

Feeds a slice of this type into the given Hasher.

impl PartialEq for GeoLocation

fn eq(&self, other: &GeoLocation) -> 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.

impl Serialize for GeoLocation

fn serialize<__S>(&self, __serializer: __S) -> Result<__S::Ok, __S::Error>

where __S: Serializer,

Serialize this value into the given Serde serializer.
