Struct ExcerptSyntax 

pub struct ExcerptSyntax {
    pub composed_start: u32,
    pub composed_end: u32,
    pub source_start: u32,
    pub handle: Arc<dyn ExcerptHighlighter>,
    pub lang: Option<&'static str>,
}

D.4.d.1.a (2026-05-29): per-visible-Document-pane build inputs for the cell-builder worker. Mirrors the shape of the top-level CellsRenderState active-doc fields but keyed by (pane_id, buffer_id) so the worker can resolve each entry’s matrix Arc via crate::editor::Editor::cells_matrix_for at publish time and rebuild per visible buffer.

K.4.7 (2026-06-07): per-excerpt syntax entry for multibuffer panes. The cells worker reads excerpt_syntax to apply per-source tree-sitter highlights across composed rows.

• composed_start / composed_end: inclusive row range in the multibuffer’s composed coordinate space.
• source_start: the first source-buffer row that maps to composed_start (used to translate highlight results back).
• handle: per-excerpt highlight provider (impl ExcerptHighlighter). Owned by MultibufferState; accessed via trait object so the host never depends on the concrete SyntaxHandle type.

Fields

composed_start: u32

composed_end: u32

source_start: u32

handle: Arc<dyn ExcerptHighlighter>

lang: Option<&'static str>

OA.7b: the excerpt’s grammar name, for its conceal rules. See lattice_cells::ExcerptHighlight::lang.
