Enum PresentPlan 

pub enum PresentPlan<'a> {
    None,
    FullFrame,
    Rects(&'a [Rect]),
}

Final presentation decision for one frame (LPAR-03 §5, §10).

Borrowed from the planner that produced it; the rect slice lives inside the InvalidationList / BufferedInvalidation storage.

Variants

None

No dirty pixels and no forced repaint. The runtime MUST NOT flush anything for this frame (LPAR-03 §5.3).

FullFrame

Repaint and flush the full logical screen. This is a first-class plan, required on overflow or unbounded dirty sources (LPAR-03 §5.4).

Rects(&'a [Rect])

Flush exactly these logical dirty rects, in order. Rects are clipped to screen bounds and pairwise disjoint under the default merge.
