Variants

Frame

Fields

cpu_frame_id: Option<u64>

Originating CPU profile sample; auxiliary/unprofiled frames have none.

scene: Scene

width: u32

height: u32

base_color: AlphaColor<Srgb>

damage_regions: Vec<Rect>

Physical-pixel rectangles. Empty means the retained target is already current and only needs presenting.

scroll_copies: Vec<DeviceCopy>

Copies within the retained target, in order, before the damage is repainted: what a scroll keeps on screen (crate::scroll_copy). A whole-surface frame ignores them.

full_redraw: bool

Resize, relayout, structure, or untracked overlay invalidation.

backdrop: BackdropFrame

The backdrops the scene’s floating surfaces were recorded over (crate::backdrop), in physical pixels. Empty draws no blur.

on_present: Option<Box<dyn FnOnce(SystemTime) + Send>>

Called with the time this frame, or the first later one, is presented.

Shutdown

Drain the channel and exit the worker loop. Sent from AppHandler::exiting; the App then join()s the handle.

Fields

keep_renderer: bool
