Struct Longitude 

pub struct Longitude(/* private fields */);

Longitude in [-180°, 180°), east positive.

Out-of-range values wrap: adding a longitude difference across the antimeridian is routine.

Implementations

impl Longitude

pub const GREENWICH: Self

Prime meridian.

pub fn from_degrees(value: f64) -> Result<Self>

Longitude from decimal degrees, east positive, wrapped.

Errors

crate::KernelError::NotFinite for NaN or infinity.

pub fn from_degrees_minutes( degrees: u16, minutes: f64, hemisphere: EastWest, ) -> Result<Self>

Longitude from whole degrees and decimal minutes.

Errors

crate::KernelError::NotFinite for NaN or infinity.

pub const fn degrees(self) -> f64

Degrees, east positive.

pub fn radians(self) -> f64

Radians.

pub fn hemisphere(self) -> EastWest

Hemisphere; Greenwich counts as east.

pub fn to_degrees_minutes(self) -> (u16, f64, EastWest)

Whole degrees, decimal minutes and hemisphere.

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

Shortest signed longitude difference to other, in [-180°, 180°), east positive.

Trait Implementations

impl Clone for Longitude

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 Longitude

impl Debug for Longitude

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

Formats the value using the given formatter.

impl Default for Longitude

fn default() -> Self

Returns the “default value” for a type.

impl Display for Longitude

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

Formats as 001°17.8'W.

impl FromStr for Longitude

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

Parses 001°17.8'W, W001 17 48, 151.2 etc.

Errors

crate::KernelError::Parse for unreadable input or a non-E/W hemisphere.

type Err = KernelError

The associated error which can be returned from parsing.

impl PartialEq for Longitude

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

Equality operator ==.

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

Inequality operator !=.

impl PartialOrd for Longitude

fn partial_cmp(&self, other: &Self) -> Option<Ordering>

This method returns an ordering between self and other values if one exists.

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

Tests less than (for self and other) and is used by the < operator.

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

Tests less than or equal to (for self and other) and is used by the <= operator.

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

Tests greater than (for self and other) and is used by the > operator.

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

Tests greater than or equal to (for self and other) and is used by the >= operator.
