A RenderOperation with no per-drawing-call state.

Required Methods

fn new(graphics: &mut Graphics<'_>) -> Self

Returns a new instance of this render operation.

fn render( &self, region: Rect<Px>, opacity: f32, graphics: &mut RenderingGraphics<'_, '_>, )

Render to graphics at rect with opacity.

This operation’s will automatically be clipped to the available space for the context it is being drawn to. The render operation should project itself into region and only use the clip rect as an optimization. To test that this is handled correctly, try placing whatever is being rendered in a Scroll widget and ensure that as the contents are clipped, the visible area shows the correct contents.

This trait is not object safe.
