  "message": "Improve UniqueVector class.\n\nThis improves the UniqueVector template class in several ways,\nwhich will be used by future CLs:\n\n- Allow custom hash and equality operators to be used for\n  the items in the set.\n\n- Make the UniqueVectorNode internal set type smaller by using\n  32-bit indices and hash values, reducing the RAM footproint of\n  each instance.\n\n- Add Contains() method, and kIndexNone value, returned by IndexOf()\n  when the value is not found, replacing the hard-coded (size_t)-1\n  value.\n\n- Add emplace_back() method for convenience.\n\n- Add a release() method to move the final vector out of the\n  instance.\n\n- Add PushBackWithIndex(), EmplaceBackWithIndex() methods to\n  perform push_back() / emplace_back() while returning a\n  (insertion_flag, item_index) value.\n\nBug: None\nChange-Id: I381cd05f5fc8fadf06d66379a1ead67c9f940267\nReviewed-on: https://gn-review.googlesource.com/c/gn/+/12701\nReviewed-by: Brett Wilson \u003cbrettw@chromium.org\u003e\nCommit-Queue: David Turner \u003cdigit@google.com\u003e\n",
