pub fn id_of(node: NodeId) -> Option<String>Expand description
Resolve a dispatched NodeId back to the app-authored .id() string that named its node
(find_by_id’s inverse, §5.5), or None for an id-less node or one no longer in the tree. The
recorder (day::record, §14.6) calls this from inside its
event observer to label a tap/input with the id an app would target in a dayscript step.
Borrow-safe: returns None rather than panicking if the tree is momentarily borrowed by a
re-entrant backend call.
