Struct CornerRadii 

pub struct CornerRadii {
    pub top_left: f64,
    pub top_right: f64,
    pub bottom_right: f64,
    pub bottom_left: f64,
}

Per-corner radii for a rounded rectangle, in the pre-transform coordinate space.

Corners are named clockwise from the top-left, matching kurbo::RoundedRectRadii — the concrete shape frust-render builds at encode time (scene-layer purity keeps the shape type itself out of this crate’s commands).

From<f64> covers the uniform case, so the one-radius callers that predate this type keep passing a bare f64 and the builder converts: CornerRadii::from(8.0) == CornerRadii::new(8.0, 8.0, 8.0, 8.0).

Fields

top_left: f64

Top-left corner radius.

top_right: f64

Top-right corner radius.

bottom_right: f64

Bottom-right corner radius.

bottom_left: f64

Bottom-left corner radius.

Implementations

impl CornerRadii

pub const fn new( top_left: f64, top_right: f64, bottom_right: f64, bottom_left: f64, ) -> Self

Radii for each corner, clockwise from the top-left (the kurbo::RoundedRectRadii::new argument order).

pub const fn uniform(radius: f64) -> Self

The same radius on all four corners — what From<f64> builds.

pub fn largest(&self) -> f64

The largest of the four corner radii.

A backend that can only express a single radius (both blurred-shadow primitives take one) lowers through this rather than through the smallest: a shadow rounded more than its caster only lightens a square corner, while one rounded less pushes a hard shadow wedge out through a rounded corner’s notch.
