Summary: X-link: https://github.com/facebook/react-native/pull/39485 Pull Request resolved: https://github.com/facebook/yoga/pull/1393 These were previously packed into structs to allow zero initializing all the flags at once without needing a ctor. C++ 20 has in-class member initializer support for bitfields, which makes these look more like normal member variables. Setting enum values is a bit jank right now, due to relying on C enums which are effectively int32_t, along with GCC `-Wconversion` being a bit aggressive in needing to explicitly mask. I have some ideas to fix this later (e.g. using scoped enums internally). bypass-github-export-checks Changelog: [General][Breaking] - Require C++ 20 when including renderer headers Reviewed By: sammy-SC Differential Revision: D49265967 fbshipit-source-id: 6ab935a866196df06e742c821f3af88eb4d18e1a
