Struct RoundedRect 

pub struct RoundedRect {
    pub rect: Rect,
    pub radii: Corners<Size>,
}

A rectangle with independently rounded corners.

Used throughout the platform for border-radius rendering, clipping regions, and hit testing. Each corner has its own elliptical radius defined as a Size (horizontal × vertical), supporting non-circular corners like border-radius: 20px / 10px.

When all four radii are zero this degenerates to a plain Rect.

Fields

rect: Rect

radii: Corners<Size>

Implementations

impl RoundedRect

pub fn new(rect: Rect, radii: Corners<Size>) -> Self

pub fn from_rect(rect: Rect) -> Self

A rounded rect with no rounding — equivalent to a plain rect.

pub fn uniform(rect: Rect, radius: f32) -> Self

All four corners share the same circular radius.

pub fn is_sharp(&self) -> bool

True when all corner radii are zero.

pub fn is_ellipse(&self) -> bool

True when the rounded rect forms a full ellipse/circle (each corner’s radius is exactly half the rect’s dimension).

pub fn normalized(self) -> Self

Scale radii down proportionally when the sum of adjacent radii exceeds the rect’s dimension. This implements the CSS spec’s corner-overlap rule.

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

Hit test: is point inside this rounded rect?

First checks the bounding rect, then tests against the elliptical corner arcs for points that fall within a corner region.

Trait Implementations

impl Clone for RoundedRect

fn clone(&self) -> RoundedRect

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for RoundedRect

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

Formats the value using the given formatter.

impl PartialEq for RoundedRect

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