Enum Paint 

#[non_exhaustive]
pub enum Paint {
    None,
    Quad(QuadPaint),
    Custom(Rc<dyn Fn(Rect, &mut Scene)>),
    Live(Rc<dyn Fn(Rect, f64, &mut Scene)>),
    Rich(Rc<dyn Fn(Rect, &mut PaintCx<'_>)>),
}

What an element draws before its children.

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.

None

Draws nothing.

Quad(QuadPaint)

A rounded rectangle.

Custom(Rc<dyn Fn(Rect, &mut Scene)>)

Arbitrary drawing into the scene, given the element’s absolute frame.

Live(Rc<dyn Fn(Rect, f64, &mut Scene)>)

Arbitrary drawing that keeps changing (spinners, pulses), without rebuilding.

Rich(Rc<dyn Fn(Rect, &mut PaintCx<'_>)>)

Arbitrary drawing that also shapes text or needs the device scale.
