Struct ShapeGeometry 

pub struct ShapeGeometry { /* private fields */ }

A [Path] plus its flattening, computed once and shared by handle.

Build one in your item’s constructor and hold it as Rc<ShapeGeometry>; SceneItem::shape then hands out clones of the handle, so the per-layout-pass cost of publishing a shape is a refcount bump rather than a flatten (or, as it used to be, a full Vec<PathCommand> copy).

Neither Send nor Sync — the memo is a OnceCell behind an Rc, like the rest of the scene.

Implementations

impl ShapeGeometry

pub fn new(path: Path) -> Self

Wrap a path. Nothing is flattened until something asks.

pub fn shared(path: Path) -> Rc<Self>

Wrap a path in a fresh shared handle — the form ItemShape::path takes.

pub fn path(&self) -> &Path

The path this geometry was built from.

pub fn outline(&self) -> &[Subpath]

The flattened outline, one [Subpath] per MoveTo run. Memoised.

pub fn bounds(&self) -> Rect

Curve-accurate AABB of the outline. Memoised. [Rect::ZERO] for an empty path.

Trait Implementations

impl Debug for ShapeGeometry

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

Formats the value using the given formatter.
