Struct PaintDamage 

pub struct PaintDamage { /* private fields */ }

Retains only draw caches; no document state, history or input is stored here.

Implementations

impl PaintDamage

pub fn record(&mut self, bounds: Rect, frame: Option<PaintFrame>)

A missing proof explicitly requests conservative full bounds.

pub fn is_recorded(&self) -> bool

Whether this draw supplied a proof or explicitly requested full bounds.

pub fn collect(&self, fallback: Rect, regions: &mut Vec<Rect>)

Collect after drawing and before mark_drawn, as the native host does.

pub fn covers_own_bounds(&self) -> bool

Whether this frame’s paint was recorded, so Self::collect covers every pixel it changed: where its parts were and are, or its whole extent then and now.

pub fn release_scene_cache(&mut self)

Drop duplicate encoded scenes when an outer cache owns the draw. Bounds remain available to clear old ink on the next full rebuild.

pub fn mark_drawn(&mut self)

Adopt only the frame the ordinary draw lifecycle accepted.
