Summary: X-link: https://github.com/facebook/react-native/pull/37115 Pull Request resolved: https://github.com/facebook/yoga/pull/1267 This is an existing bitset enum in the API. Use the facility added in the last diff to add flag operators to it, to avoid the need for casting, and to make it clearer in the generated YGEnums.h that it is a bitset. Reviewed By: rshest Differential Revision: D45341504 fbshipit-source-id: 0b80588f3e2e167d4c1c722c6d6608408dd617ba
