Struct BatchRects 

pub struct BatchRects {
    batch: PictureRect,
    items: Option<Vec<PictureRect, FrameAllocator>>,
    allocator: FrameAllocator,
}

Fields

batch: PictureRect

Union of all of the batch’s item rects.

Very often we can skip iterating over item rects by testing against this one first.

items: Option<Vec<PictureRect, FrameAllocator>>

When the batch rectangle above isn’t a good enough approximation, we store per item rects.

allocator: FrameAllocator

Implementations

impl BatchRects

fn new(allocator: FrameAllocator) -> Self

fn add_rect(&mut self, rect: &PictureRect)

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