Struct geod_types::Longitude

pub struct Longitude<A: Angle>(_);

The angle measured on the equatorial plane between the meridian of the point and the prime meridian (Greenwich, UK). .

Implementations

impl<A: Angle> Longitude<A>

pub fn east<T>(to_angle: T) -> Result<Self, A::NumErr> where
    T: TryInto<A, Error = A::NumErr>, 

Construct an eastern longitude with some numeric information.

Errors

• cannot construct an angle from the given information (overflow of some kind)
• the constructed angle is more than the straight angle. Valid longitude is in the range 0 <= lon <= 180 deg.

pub fn west<T>(to_angle: T) -> Result<Self, A::NumErr> where
    T: TryInto<A, Error = A::NumErr>, 

Construct a western longitude with some numeric information.

Errors

• cannot construct an angle from the given information (overflow of some kind)
• the constructed angle is more than the straight angle. Valid longitude is in the range 0 <= lon <= 180 deg.

pub fn prime() -> Self

The chosen by convention 0-meridian

pub fn anti_meridian() -> Self

The longitude opposite to the prime

pub fn angle(self) -> A

Angle between the longitude and the prime meridian (absolute value of the longitude).

pub fn direction(self) -> Option<RotationalDirection>

In which direction (from the prime) should we move to reach the longitude faster

pub fn opposite(self) -> Self

Diametrically opposite meridian which together with the current one defines the hemisphere (great circle)
