Struct AtlasRegion 

pub struct AtlasRegion {
    pub layer: u32,
    pub offset: [u32; 2],
    pub size: [u32; 2],
}

Where one image’s texels live in the atlas array.

Hashable because the pending-clear list carries a set index beside it: the same rectangle can reach ImageResidency::evictions twice before a single clear has been serviced, and the dedup that keeps it reported once must not be a linear scan of a list that grows with the churn rate.

Fields

layer: u32

Array layer holding the region.

offset: [u32; 2]

Pixel offset of the region’s top-left corner within that layer.

size: [u32; 2]

Region extent in pixels.
