Struct Deviation 

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

Compass deviation: the angle from magnetic north to compass north.

Positive is easterly. Magnetic course = compass course + deviation.

Implementations

impl Deviation

pub const ZERO: Self

No deviation.

pub fn new(degrees: f64) -> Result<Self>

Creates a deviation from a value in [-180.0, 180.0] degrees.

Errors

Returns NavigationError::NotFinite for NaN or an infinity, and NavigationError::OutOfRange outside [-180.0, 180.0].

pub const fn degrees(self) -> f64

The deviation in degrees, positive easterly.

Trait Implementations

impl Clone for Deviation

fn clone(&self) -> Deviation

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Copy for Deviation

impl Debug for Deviation

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

Formats the value using the given formatter.

impl Default for Deviation

fn default() -> Deviation

Returns the “default value” for a type.

impl Display for Deviation

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

impl PartialEq for Deviation

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

Equality operator ==.

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

Inequality operator !=.

impl PartialOrd for Deviation

fn partial_cmp(&self, other: &Deviation) -> 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.
