Struct Position 

pub struct Position { /* private fields */ }

Position on the Earth’s surface (WGS 84).

Implementations

impl Position

pub const ORIGIN: Self

0°N 0°E.

pub const fn new(latitude: Latitude, longitude: Longitude) -> Self

Position from latitude and longitude.

pub fn from_degrees(latitude: f64, longitude: f64) -> Result<Self>

Position from decimal degrees.

Errors

As Latitude::from_degrees and Longitude::from_degrees.

pub const fn latitude(self) -> Latitude

Latitude.

pub const fn longitude(self) -> Longitude

Longitude.

pub fn latitude_difference(self, other: Self) -> Angle

Latitude difference to other, north positive.

pub fn longitude_difference(self, other: Self) -> Angle

Longitude difference to other, east positive, short way.

pub fn departure(self, other: Self) -> Distance

Departure: east-west distance between the meridians at the mean latitude.

Plane-sailing approximation, for short distances.

pub fn to_geocentric_unit(self) -> GeocentricUnit

Position as a geocentric direction; the form spherical geometry is computed in. See GeocentricUnit for the axes.

pub fn from_geocentric_unit(unit: GeocentricUnit) -> Self

Position of a geocentric direction.

Infallible: the zero vector cannot be a GeocentricUnit.

Trait Implementations

impl Clone for Position

fn clone(&self) -> Self

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Copy for Position

impl Debug for Position

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

Formats the value using the given formatter.

impl Default for Position

fn default() -> Self

Returns the “default value” for a type.

impl Display for Position

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

Formats as 50°45.3'N 001°17.8'W.

impl FromStr for Position

fn from_str(input: &str) -> Result<Self>

Parses latitude then longitude.

50°45.3'N 001°17.8'W, N50 45.3 W001 17.8, 50.755, -1.2967.

Errors

crate::KernelError::Parse if the halves cannot be separated or either is unreadable.

type Err = KernelError

The associated error which can be returned from parsing.

impl PartialEq for Position

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

Equality operator ==.

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

Inequality operator !=.
