Struct DirtyRegion

pub struct DirtyRegion { /* private fields */ }

A region composed of a few rectangles that need to be redrawn.

Implementations

impl DirtyRegion

pub fn iter(&self) -> impl Iterator<Item = Box2D<Coord, LogicalPx>> + '_

An iterator over the part of the region (they can overlap)

pub fn add_rect(&mut self, rect: LogicalRect)

Add a rectangle to the region.

Note that if the region becomes too complex, it might be simplified by being bigger than the actual union.

pub fn add_box(&mut self, b: Box2D<Coord, LogicalPx>)

Add a box to the region

Note that if the region becomes too complex, it might be simplified by being bigger than the actual union.

pub fn union(&self, other: &Self) -> Self

Make an union of two regions.

Note that if the region becomes too complex, it might be simplified by being bigger than the actual union

pub fn bounding_rect(&self) -> LogicalRect

Bounding rectangle of the region.

pub fn intersection(&self, other: LogicalRect) -> DirtyRegion

Intersection of a region and a rectangle.
