Enum PlanePath 

#[non_exhaustive]
pub enum PlanePath {
    AtomicCursor,
    AtomicOverlay,
    Legacy,
}

How the cursor reaches the screen.

Variants (Non-exhaustive)

Non-exhaustive enums could have additional variants added in future. Therefore, when matching against variants of non-exhaustive enums, an extra wildcard arm must be added to account for any future variants.

AtomicCursor

A dedicated cursor plane, driven atomically.

The best case: per-CRTC hardware with no z-ordering to negotiate.

AtomicOverlay

An overlay plane, driven atomically.

For hardware with no cursor plane, or whose cursor plane can take none of CURSOR_FORMATS. Costs an overlay the compositor might have wanted.

Legacy

drmModeSetCursor, the legacy path.

No atomic commit, so the cursor cannot be coalesced with a frame and cannot be rotated. Last resort.
