  "message": "Do not recalculate BalsaHeaders::iterator_base::value_ unless necessary.\n\nFrequently there are back-to-back it-\u003efirst and it-\u003esecond calls.  By making\n`value_` an absl::optional\u003c\u003e type, it is possible to avoid recalculating it on\nevery Lookup() call.\n\n`value_` is initialized to absl::nullopt upon construction.  It is copied by the\nimplicit copy assignment operator and copy constructor, and will contain the\ncorrect views into `*header_`.  It is now reset upon iterator increment.  There\nshould be no other ways to mutate the iterator.\n\nPiperOrigin-RevId: 446239817\n",
