Used by draw_arc and draw_sector.

Implementations

impl Angle

pub const FULL_CIRCLE: Angle = _

The 360° angle.

pub const HALF_CIRCLE: Angle = _

The 180° angle.

pub const QUARTER_CIRCLE: Angle = _

The 90° angle.

pub const ZERO: Angle = _

The 0° angle.

pub fn from_degrees(d: f32) -> Self

An angle in degrees where 360.0 is the full circle.

pub fn from_radians(r: f32) -> Self

An angle in radians where TAU (doubled PI) is the full circle.

pub fn abs(self) -> Self

Convert the angle to an absolute (non-negative) value.

pub fn normalize(self) -> Self

Normalize the angle to less than one full rotation (in the range 0°..360°).

pub fn to_degrees(self) -> f32

Get the angle value in degrees where 360.0 is the full circle..

pub fn to_radians(self) -> f32

Get the angle value in radians where TAU (doubled PI) is the full circle.

pub fn sin(&self) -> f32

Approximates sin(x) of the angle with a maximum error of 0.002.

pub fn cos(&self) -> f32

Approximates cos(x) of the angle with a maximum error of 0.002.

pub fn tan(&self) -> f32

Approximates tan(x) of the angle with a maximum error of 0.6.

Trait Implementations

impl Add for Angle

type Output = Angle

The resulting type after applying the + operator.

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

Performs the + operation.

impl AddAssign for Angle

fn add_assign(&mut self, other: Angle)

Performs the += operation.

impl Clone for Angle

fn clone(&self) -> Angle

Returns a copy 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 Default for Angle

fn default() -> Angle

Returns the “default value” for a type.

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

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 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

This method tests less than (for self and other) and is used by the < operator.

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

This method tests less than or equal to (for self and other) and is used by the <= operator.

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

This method tests greater than (for self and other) and is used by the > operator.

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

This method tests greater than or equal to (for self and other) and is used by the >= operator.

impl Sub for Angle

type Output = Angle

The resulting type after applying the - operator.

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

Performs the - operation.

impl SubAssign for Angle

fn sub_assign(&mut self, other: Angle)

Performs the -= operation.

impl Copy for Angle
