Enum Shape 

#[non_exhaustive]
pub enum Shape {
    Rect {
        width: f32,
        height: f32,
        fill: u32,
        stroke: Option<Stroke>,
        corner_radius: f32,
    },
    Polygon {
        points: Vec<(f32, f32)>,
        fill: u32,
        stroke: Option<Stroke>,
    },
    Path {
        data: String,
        fill: u32,
        stroke: Option<Stroke>,
    },
}

Vector shape primitive.

Variants (Non-exhaustive)

Non-exhaustive enums could have additional variants added in future. Therefore, when matching against variants of non-exhaustive enums, an extra wildcard arm must be added to account for any future variants.

Implementations

impl Shape

pub const fn rect(width: f32, height: f32) -> Self

Zero-size placeholder rect with no fill. Used by SceneObject::default.

pub fn content_size(&self) -> Option<(f32, f32)>

Object-local content extent — the (width, height) of the minimal axis-aligned box that contains the shape’s geometry in its own coordinate system (before any Transform is applied).

• Shape::Rect reports its declared (width, height) verbatim. A rounded rect with corner_radius > 0 still has the same outer bound; the rounding only carves area away inside the box.
• Shape::Polygon reports the bounding box of its points list. An empty polygon reports (0.0, 0.0).
• Shape::Path is parsed by crate::svg_path::parse_bbox and reports the AABB of every anchor / control point. This is the convex-hull-of-control-points superset of the painted curve (an exact tight bound would walk the derivative roots); it is what scene-layer layout queries actually want. Returns None for empty / unparseable data.

Stroke half-widths are NOT included; the bounds reflect the filled geometry only. A rasteriser that needs the stroked silhouette must inflate the result by stroke.width / 2.

Trait Implementations

impl Clone for Shape

fn clone(&self) -> Shape

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for Shape

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

Formats the value using the given formatter.
