Struct CppFieldOwnerIndex 

pub struct CppFieldOwnerIndex { /* private fields */ }

Which owners the parse product already holds field declarations for, folded in as the walk records them.

CppVisitor::has_enum_enumerator_units asks that question once per enum and used to answer it by scanning every declaration accumulated so far: O(enums x declarations) on exactly the generated headers that declare many of both (#2786). The answer only grows by declaration, so the walk carries it. A field’s short name names its owner chain, Owner.member, so one field answers for every dotted prefix of its own short name; an anonymous enum’s or union’s enumerators carry bare short names instead (#2140), which is what an empty owner short name asks about.
