Struct CircleSegment

pub struct CircleSegment {
    pub center: Point,
    pub outer_radius: f64,
    pub inner_radius: f64,
    pub start_angle: f64,
    pub sweep_angle: f64,
}

A segment of a circle.

If inner_radius > 0, then the shape will be a doughnut segment.

Fields

center: Point

The center.

outer_radius: f64

The outer radius.

inner_radius: f64

The inner radius.

start_angle: f64

The angle to start drawing the segment (in radians).

sweep_angle: f64

The arc length of the segment (in radians).

Implementations

impl CircleSegment

pub fn new( center: impl Into<Point>, outer_radius: f64, inner_radius: f64, start_angle: f64, sweep_angle: f64, ) -> Self

Create a CircleSegment out of its constituent parts.

pub fn outer_arc(&self) -> Arc

Return an arc representing the outer radius.

pub fn inner_arc(&self) -> Arc

Return an arc representing the inner radius.

This is reversed from the outer arc, so that it is in the same direction as the arc that would be drawn (as the path elements for this circle segment produce a closed path).

pub fn is_finite(&self) -> bool

Is this circle segment finite?

pub fn is_nan(&self) -> bool

Is this circle segment NaN?

Trait Implementations

impl Add<Vec2> for CircleSegment

type Output = CircleSegment

The resulting type after applying the + operator.

fn add(self, v: Vec2) -> Self

Performs the + operation.

impl Clone for CircleSegment

fn clone(&self) -> CircleSegment

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for CircleSegment

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

Formats the value using the given formatter.

impl PartialEq for CircleSegment

fn eq(&self, other: &CircleSegment) -> 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 Shape for CircleSegment

type PathElementsIter<'iter> = Chain<Chain<Chain<Chain<Once<PathEl>, Once<PathEl>>, ArcAppendIter>, Once<PathEl>>, ArcAppendIter>

The iterator returned by the path_elements method.

fn path_elements( &self, tolerance: f64, ) -> Chain<Chain<Chain<Chain<Once<PathEl>, Once<PathEl>>, ArcAppendIter>, Once<PathEl>>, ArcAppendIter>

Returns an iterator over this shape expressed as PathEls; that is, as Bézier path elements.

fn area(&self) -> f64

Signed area.

fn perimeter(&self, _accuracy: f64) -> f64

Total length of perimeter.

fn winding(&self, pt: Point) -> i32

The winding number of a point.

fn bounding_box(&self) -> Rect

The smallest rectangle that encloses the shape.

fn to_path(&self, tolerance: f64) -> BezPath

Convert to a Bézier path.

fn into_path(self, tolerance: f64) -> BezPath

where Self: Sized,

Convert into a Bézier path.

fn path_segments(&self, tolerance: f64) -> Segments<Self::PathElementsIter<'_>>

Returns an iterator over this shape expressed as Bézier path segments (PathSegs).

fn contains(&self, pt: Point) -> bool

Returns true if the Point is inside this shape.

fn as_line(&self) -> Option<Line>

If the shape is a line, make it available.

fn as_rect(&self) -> Option<Rect>

If the shape is a rectangle, make it available.

fn as_rounded_rect(&self) -> Option<RoundedRect>

type Output = CircleSegment

The resulting type after applying the - operator.

fn sub(self, v: Vec2) -> Self

Performs the - operation.
