The Degrees newtype an f64.

Tuple Fields

0: f64

Implementations

impl Degrees

pub fn normalise(&self) -> Self

Normalise a Degrees into the range: -180 < value <= 180

Examples

use angle_sc::Degrees;

assert_eq!(0.0, Degrees(-360.0).normalise().0);
assert_eq!(180.0, Degrees(-180.0).normalise().0);
assert_eq!(180.0, Degrees(180.0).normalise().0);
assert_eq!(0.0, Degrees(360.0).normalise().0);

pub fn abs(self) -> Self

The absolute value of the angle.

pub fn opposite(self) -> Self

The opposite angle on the circle, i.e. +/- 180 degrees.

Trait Implementations

impl Add for Degrees

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

Add a pair of angles in Degrees, wraps around +/-180.

Examples

use angle_sc::{Degrees};

let angle_120 = Degrees(120.0);
let result = angle_120 + angle_120;
assert_eq!(-angle_120, result);

type Output = Degrees

The resulting type after applying the + operator.

impl Clone for Degrees

fn clone(&self) -> Degrees

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for Degrees

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

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for Degrees

fn deserialize<__D>(__deserializer: __D) -> Result<Self, __D::Error>

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl From<Angle> for Degrees

fn from(a: Angle) -> Self

Convert an Angle to Degrees.

impl From<Degrees> for Angle

fn from(a: Degrees) -> Self

Construct an Angle from an angle in Degrees.
In order to minimize round-off errors, this function calculates sines of angles with sine values <= 1 / sqrt(2): see https://stackoverflow.com/questions/31502120/sin-and-cos-give-unexpected-results-for-well-known-angles
It is based on GeographicLib::Math::sincosd function.

impl From<Radians> for Degrees

fn from(a: Radians) -> Self

Create an angle in Degrees from an angle in Radians.

Examples

use angle_sc::{Degrees, Radians};

let arg = Radians(core::f64::consts::FRAC_PI_2);
let answer = Degrees::from(arg);
assert_eq!(90.0, answer.0);

impl Neg for Degrees

fn neg(self) -> Self

An implementation of Neg for Degrees, i.e. -angle.

Examples

use angle_sc::Degrees;

let angle_45 = Degrees(45.0);
let result_m45 = -angle_45;
assert_eq!(-45.0, result_m45.0);

type Output = Degrees

The resulting type after applying the - operator.

impl PartialEq for Degrees

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

This method tests for self and other values to be equal, and is used by ==.

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

This method tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.

impl Serialize for Degrees

fn serialize<__S>(&self, __serializer: __S) -> Result<__S::Ok, __S::Error>

where __S: Serializer,

Serialize this value into the given Serde serializer.

impl Sub for Degrees

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

Subtract a pair of angles in Degrees, wraps around +/-180.

Examples

use angle_sc::{Degrees};

let angle_120 = Degrees(120.0);
let result = -angle_120 - angle_120;
assert_eq!(angle_120, result);

type Output = Degrees

The resulting type after applying the - operator.
