Struct StaticOverlayQuads 

Source 
pub struct StaticOverlayQuads {
    pub quads: Arc<[Vec<RowOverlayQuad>]>,
    pub computed_for_key: VisibleHighlightsKey,
}
Expand description

Perf plan B.2: worker-published per-row pre-bucketed static-overlay quads for the active pane’s visible window.

quads[i] is the per-row tagged quad list for visible line i (i.e. doc line scroll + i). Each entry tags its overlay layer (OverlayLayer) so the renderer can interleave cursor-coupled layers (current_match, visual_range) in the right precedence order at prepaint time.

Active-pane only — inactive panes keep the legacy per-frame bucket path. The cell is published on every overlay-worker recompute and invalidates on its own axis (VisibleHighlightsKey::static_overlay_version) so a search-query bump re-buckets without touching unrelated state.

Fields§

§quads: Arc<[Vec<RowOverlayQuad>]>

Arc<[T]> per the D.1 pattern — HOLD / partial-reuse paths bump the outer Arc instead of cloning the per-row Vecs. Typical viewport (120 rows) × typical quads/row (≤ a few per layer) keeps this comfortably small.
