Struct Angle 

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

Provides calculation of angles. As the angle is 0, the direction is the negative y-axis.

Implementations

impl Angle

pub fn new(radian: f64) -> Self

Create an angle from the radian.

pub fn radian(&self) -> f64

Get the radian.

pub fn opposite(&self) -> Self

Get opposite angle.

pub fn right_clockwise(&self) -> Self

Get the clockwise right angle.

pub fn right_counterclockwise(&self) -> Self

Get the counterclockwise right angle.

pub fn unit_x(&self) -> f64

pub fn unit_y(&self) -> f64

pub fn iter_range_around(&self, radian_range: f64, step_num: usize) -> AngleIter

Create an iterator of angles around the specified angle.

Trait Implementations

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 Debug for Angle

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

Formats the value using the given formatter.

impl PartialEq for Angle

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

impl Copy for Angle
