Struct Ring 

pub struct Ring { /* private fields */ }

A annulus or closed annular sector with opposite-winding inner contour.

Implementations

impl Ring

pub fn new(center: Point, inner_radius: f64, outer_radius: f64) -> Self

Builds a complete ring with 0 <= inner <= outer.

pub fn sweep(self, start_angle: f64, sweep_angle: f64) -> Self

Selects a clockwise-positive annular sector in radians; clamps to one turn.

Trait Implementations

impl Clone for Ring

fn clone(&self) -> Self

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for Ring

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

Formats the value using the given formatter.

impl Shape for Ring

fn path(&self) -> Result<Path2D, ValidationError>

Returns a checked path snapshot without f32 narrowing.

fn bounding_box(&self) -> Result<Rect, ValidationError>

Geometric bounds; defaults to the path’s cached curve bounds.

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

Exact rectangle equivalent, when available, for a rule-independent fast path.

fn fill(self, paint: impl Into<Paint>) -> Styled<Self>

where Self: Sized,

Adds floating fill paint, using the nonzero rule by default.

fn stroke(self, width: f64, paint: impl Into<Paint>) -> Styled<Self>

where Self: Sized,

Adds a bounded curve/path stroke without an implicit fill.
