matbech · web-flow · commit c4cf531f6a8e · 2026-05-31T20:07:50.000-07:00
Added missing constexpr to is_guid_of helper. guid_of is already constexpr: constexpr:https://github.com/microsoft/cppwinrt/blob/55f1b452aca069d6ac7eaad3e05cc1058fc39d27/strings/base_identity.h#L8 and find_iid_traits::test is constexpr and calls is_guid_of: https://github.com/microsoft/cppwinrt/blob/55f1b452aca069d6ac7eaad3e05cc1058fc39d27/strings/base_implements.h#L397
