  "message": "cpp: allow casting C++ struct reference types to C types\n\nThis is safe because the C++ layout is static_assert\u0027ed to be the\nsame as the C layout. It removes bad-looking reinterpret_cast\nfrom application code.\n\nMutable reference casts are not allowed. This is because:\n - Some C++ structs have RAII objects in them. Casting to C and\n   then changing the members could cause unexpected lifetime\n   changes\n - Structs with \"free members\" functions only get const conversion\n   operators. This is because output structs like this have RAII data\n   which should not be mutated. The C structs do not have\n   const-qualified members, so conversion to a mutable C struct would\n   be unsafe.\n\nBug: chromium:40195122\nChange-Id: I18cd06b04da2ea34803f517e2b640ceaaba408af\nReviewed-on: https://dawn-review.googlesource.com/c/dawn/+/185966\nReviewed-by: Kai Ninomiya \u003ckainino@chromium.org\u003e\nCommit-Queue: Austin Eng \u003cenga@chromium.org\u003e\nReviewed-by: Loko Kung \u003clokokung@google.com\u003e\n",
