  "message": "[dawn] Add nullable support to return types\n\nChange return types to be more like RecordMember (type, annotation,\noptional) rather than a raw Type. This requires a bunch of refactoring,\nbut now allows attaching that info to return types.\n\n- Introduce a base class of RecordMember called AnnotatedTypedMember\n  that only has type, annotation, optional, and json_data.\n- Change the representation of function/method return types from a Type\n  `.return_type` to an AnnotatedTypedMember `.returns`.\n- Change the representation of void return to `None` instead of\n  `types[\u0027void\u0027]`.\n- Change the return type of CreateBuffer from \"buffer\" to\n  {\"type\": \"buffer\", \"optional\": true}.\n\nBug: 427657664\nChange-Id: Ifc3197139cdb3de5914c6bb33dd1b1c2dd20f1ce\nReviewed-on: https://dawn-review.googlesource.com/c/dawn/+/249394\nReviewed-by: Corentin Wallez \u003ccwallez@chromium.org\u003e\nCommit-Queue: Kai Ninomiya \u003ckainino@chromium.org\u003e\nReviewed-by: Loko Kung \u003clokokung@google.com\u003e\n",
