pub fn cpp_reconcile_group_key(fq_name: &str) -> Option<CppReconcileGroupKey>Expand description
Which member identifier and owner terminal a queried canonical name asks
about, or None when the name has no terminal segment to probe with.
Parsed through the sanctioned input-edge parser rather than split here, and
note $ is not a segment boundary for it – a nested owner chain stays one
segment, so the terminal really is the member.
