Enum VectorShape 

#[non_exhaustive]
pub enum VectorShape {
    Rect {
        rect: Rect,
    },
    RoundedRect {
        rect: Rect,
        radius: f32,
    },
    Circle {
        center: Vec2,
        radius: f32,
    },
    Ellipse {
        center: Vec2,
        half_extents: Vec2,
    },
    Path {
        points: Vec<Vec2>,
    },
}

Geometric shape — no paint, no transform. The “what” of a vector 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.

Rect

Sharp-corner rectangle in NDC.

Fields

rect: Rect

Axis-aligned bounding rect.

RoundedRect

Rounded rectangle in NDC.

Fields

rect: Rect

Axis-aligned bounding rect.

radius: f32

Corner radius in NDC units.

Circle

Circle in NDC.

Fields

center: Vec2

Center, NDC.

radius: f32

Radius, NDC.

Ellipse

Anisotropic ellipse in NDC.

Fields

center: Vec2

Center, NDC.

half_extents: Vec2

Half-extents (a, b) of the implicit equation (x/a)² + (y/b)² = 1.

Path

Closed polygon in NDC. Up to 32 vertices honored by the mask path (matching path_clip.wgsl’s uniform cap).

Fields

points: Vec<Vec2>

Vertex list. Vec (not slice) so the variant is owned; pay the allocation once per shape construction.

Implementations

impl VectorShape

pub fn rect(rect: Rect) -> Self

Convenience constructor.

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

Convenience constructor.

pub fn circle(center: Vec2, radius: f32) -> Self

Convenience constructor.

pub fn ellipse(center: Vec2, half_extents: Vec2) -> Self

Convenience constructor.

pub fn path(points: Vec<Vec2>) -> Self

Convenience constructor.

pub fn bounds(&self) -> Rect

Axis-aligned bounding rect of the shape. For paths, computed from the point list (returns a zero rect for an empty path).

pub fn as_mask_shape(&self) -> Option<MaskShape>

If this shape has an analytic SDF (rect / rounded / circle / ellipse), return it as a MaskShape so the existing mask / clip / privacy-blur / redaction / spotlight machinery can consume it directly. Returns None for Self::Path — callers should use the path-clip / path-mask-texture variants instead.

pub fn as_path_points(&self) -> Option<&[Vec2]>

If this is a path, return the points slice. Returns None for analytic SDF shapes.

Trait Implementations

impl Clone for VectorShape

fn clone(&self) -> VectorShape

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for VectorShape

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

Formats the value using the given formatter.

impl PartialEq for VectorShape

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