Enum OverlayLayer 

Source 
pub enum OverlayLayer {
    DocHighlight,
    AllMatches,
    Substitute,
}
Expand description

Perf plan B.2: overlay layer tag carried on each per-row pre-bucketed quad in StaticOverlayQuads. The renderer uses the tag to interleave cursor-coupled layers (current_match, visual_range) at the right precedence at prepaint time:

doc_highlight  →  all_matches  →  current_match  →  visual  →  substitute

Push order = paint order = visual precedence (paint_quad overwrites; later quads in each row’s Vec win).

Variants§

§

DocHighlight

LSP textDocument/documentHighlight ranges — symbol occurrences under the cursor. Cursor-settle cadence (the LSP returns a new response after the cursor lands on a new symbol); we treat it as static across cursor blinks.

§

AllMatches

hlsearch matches across the active document. Bumps on text_version edits and search-query changes.

§

Substitute

:s/pat/repl/ preview overlay. Bumps as the substitute command line is typed.
