Struct VirtualRowsRenderState 

pub struct VirtualRowsRenderState {
    pub matrix: Arc<VirtualRowMatrix>,
    pub pane_matrices: Arc<HashMap<PaneId, Arc<ArcSwap<VirtualRowMatrix>>>>,
}

D.3.b.1 (2026-05-29): renderer-side projection of the virtual-rows worker’s published VirtualRowMatrix. Carries the matrix so the TUI / GPUI renderer can interleave virtual rows between document rows when painting visible content.

matrix defaults to an empty VirtualRowMatrix so the renderer never has to handle an Option; an empty matrix reports no rows for any line.

Fields

matrix: Arc<VirtualRowMatrix>

pane_matrices: Arc<HashMap<PaneId, Arc<ArcSwap<VirtualRowMatrix>>>>

D.4.d.2.1.d (2026-05-30): PaneId → virtual-rows matrix lookup derived from CellsRenderState::panes at publish time so renderers can find a pane’s virtual-rows matrix by id without scanning the panes slice. One entry per visible Document leaf; non-Document panes are absent (the publisher filters them out of CellsRenderState::panes). Mirror of CellsRenderState::pane_matrices.

Use Self::matrix_for_pane for the read; direct access to the map is fine when batching multiple lookups.

Implementations

impl VirtualRowsRenderState

pub fn matrix_for_pane( &self, pane_id: PaneId, ) -> Option<&Arc<ArcSwap<VirtualRowMatrix>>>

D.4.d.2.1.d: look up the virtual-rows matrix cell for pane_id. Returns None when the pane is not a Document leaf (file tree / help / messages / oil / terminal panes skip the cells path entirely, so they’re absent from pane_matrices — see crate::dispatch::Editor::build_cells_panes). Mirror of CellsRenderState::matrix_for_pane.
