Trait Implementations

impl IDirtyRectCollector for RegionDirtyRectTracker

fn add_rect(&self, rect: LtrbRect)

impl IDirtyRectTracker for RegionDirtyRectTracker

fn finalize_frame(&self, _bounds: LtrbRect)

Post-processes the dirty rect area (e. g. to account for anti-aliasing)

fn begin_draw(&self, ctx: &mut dyn IDrawingContextImpl)

Pushes the dirty area as a clip onto ctx.

fn end_draw(&self, ctx: &mut dyn IDrawingContextImpl)

Pops the clip pushed by begin_draw.

fn is_empty(&self) -> bool

fn intersects(&self, rect: LtrbRect) -> bool

fn initialize(&self, _bounds: LtrbRect)

fn visualize(&self, context: &mut dyn IDrawingContextImpl)

Draws the dirty area in a random color (debug overlay).

fn combined_rect(&self) -> LtrbRect

fn is_single_dirty_rect_tracker(&self) -> bool

Whether the tracker is a SingleDirtyRectTracker (the is test of the render pass, which needs no per-visual test with one).
