Struct CppRecoveryCapture 

pub struct CppRecoveryCapture { /* private fields */ }

What one open CppVisitor::record_recovered_declarations has watched happen to the declaration set.

The recovered set used to be a difference against a clone of the whole declaration set, taken once per recovery: O(recoveries x declarations) on exactly the error-recovered files that already walk slowest (#2787). The walk knows which declarations it creates, so the capture collects them as they are made and the difference is never needed.

removed_pre_existing is what makes that equal to the difference. A deferred replacement removes the replaced declaration’s children (ParsedFile::prepare_deferred_replacement), and the reparse walk then re-creates them. Creation alone cannot tell that apart from a first mint, so a removal of a declaration this capture did not create records that it was already there when the capture opened.
