Struct Angle 

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

A plain angular magnitude, in degrees.

Unlike crate::Direction this is not a compass direction and is not wrapped into [0°, 360°): it is a difference, an error, or a subtended angle, and its sign carries meaning. Use it for gyro error, sextant angles, leeway and the like.

Implementations

impl Angle

pub const ZERO: Self

A zero angle.

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

Creates an angle from degrees.

Errors

Returns NavigationError::NotFinite for NaN or an infinity.

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

Creates an angle from minutes of arc.

Errors

Returns NavigationError::NotFinite for NaN or an infinity.

pub fn from_degrees_minutes_seconds( degrees: f64, minutes: f64, seconds: f64, ) -> Result<Self>

Creates an angle from degrees, minutes and seconds of arc.

Errors

Returns NavigationError::NotFinite for NaN or an infinity.

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

Creates an angle from radians.

Errors

Returns NavigationError::NotFinite for NaN or an infinity.

pub const fn degrees(self) -> f64

The angle in degrees.

pub fn minutes(self) -> f64

The angle in minutes of arc.

pub fn radians(self) -> f64

The angle in radians.

pub fn abs(self) -> Self

The magnitude of the angle.

pub fn normalised(self) -> Self

The angle folded into [-180°, 180°).

Trait Implementations

impl Add for Angle

type Output = Angle

The resulting type after applying the + operator.

fn add(self, other: Self) -> Self

Performs the + operation.

impl Clone for Angle

fn clone(&self) -> Angle

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Copy for Angle

impl Debug for Angle

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

Formats the value using the given formatter.

impl Default for Angle

fn default() -> Angle

Returns the “default value” for a type.

impl Display for Angle

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

Formats the value using the given formatter.

impl FromStr for Angle

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

Reads 1°30.5', 1 30 30, -2.7 and the like.

An angle has no hemisphere, so only a sign is accepted.

Errors

Returns NavigationError::Parse for anything unreadable, including a hemisphere letter.

type Err = NavigationError

The associated error which can be returned from parsing.

impl Neg for Angle

type Output = Angle

The resulting type after applying the - operator.

fn neg(self) -> Self

Performs the unary - operation.

impl PartialEq for Angle

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

Equality operator ==.

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

Inequality operator !=.

impl PartialOrd for Angle

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

impl StructuralPartialEq for Angle

impl Sub for Angle

type Output = Angle
