Volt.Dev.Error (Volt v0.19.4)

JSON-safe error entries for the development error overlay.

Build errors arrive as OXC.Diagnostic maps, compiler messages, exceptions, or arbitrary terms. entries/2 turns any of them into maps the browser overlay renders, with a source frame when the file and line are known.

With the optional :lumis dependency and a Lumis parser package for the file's language, such as :lumis_wasm_typescript, entries also carry frame_html, the frame with syntax highlighting.
