Module style 

Syntax-highlight style types and the ExcerptHighlighter trait.

Moved from lattice-syntax so that lattice-runtime (which defines the Document trait) can reference ExcerptHighlighter without pulling in lattice-syntax — which has a transitive dep on lattice-mode → lattice-runtime (cycle). lattice-cells has no lattice deps, breaking the chain cleanly.

lattice-syntax re-exports everything from here so call-sites outside lattice-cells / lattice-runtime see no path change.

Structs

ExcerptHighlight

Per-excerpt entry produced by [Document::excerpt_highlights].

RefineSpan

DR.2 (2026-08-12): a byte range whose background differs from its row’s — intra-line diff refinement.

StyledSpan

Byte-range span within one source line, carrying a semantic Style.

Enums

RefineKind

Which side of a refined pair a RefineSpan belongs to. Picks the theme element, and nothing else.

Style

Semantic style category emitted by the tree-sitter highlighter.

Traits

ExcerptHighlighter

Trait implemented by SyntaxHandle (and future highlight providers). Used by Document::excerpt_highlights so that lattice-runtime can expose per-excerpt highlighting through the Document trait without taking a direct dep on lattice-syntax.
