Enum CompassReference

pub enum CompassReference {
    TrueNorth,
    MagneticNorth,
    East,
}

The “zero” reference point for a compass needle

Variants

TrueNorth

0 is True North - the geometric north pole (axis of rotation)

MagneticNorth

0 is Magnetic North - the direction that a compass needle points

East

0 is East - Used mostly for X/Y cartesian planes where angles are 0 to the right

Trait Implementations

impl Clone for CompassReference

fn clone(&self) -> CompassReference

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for CompassReference

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

Formats the value using the given formatter.

impl Default for CompassReference

fn default() -> CompassReference

Returns the “default value” for a type.

impl FromUnits<Angle> for CompassReference

fn from(&self, value: Angle, units: Self) -> Angle

Converts the value with unit units into this (self) unit

impl PartialEq for CompassReference

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