pub async fn updater_check(app: AppHandle) -> Result<UpdateStatus, AppError>Expand description
Check the configured update endpoint for a newer release.
Emits updater:status events:
{ "status": "checking" }— immediately on entry.{ "status": "available", "version": "…", "notes": "…" }— when a newer version is found.{ "status": "upToDate" }— when already on latest.{ "status": "error", "message": "…" }— on any failure.
Returns the final UpdateStatus for callers who prefer a synchronous result
(the frontend can use either the return value or the events).
