 // The implementation of a GoogleMock matcher which can be used to compare a
 // std::vector<std::unique_ptr<WebSocketFrame>>* against an expectation defined
 // as an
 // array of InitFrame objects. Although it is possible to compose built-in
 // GoogleMock matchers to check the contents of a WebSocketFrame, the results
 // are so unreadable that it is better to use this matcher.
