If D supports this extension (similar to class) as below

    FileIdBothDirectoryInfo,
    FileIdBothDirectoryRestartInfo,
    FileIoPriorityHintInfo,
    FileRemoteProtocolInfo,
    FileFullDirectoryInfo,
    FileFullDirectoryRestartInfo,
}

enum(FILE_INFO_BY_HANDLE_CLASS_NTDDI_WIN10_RS1)

     FileCaseSensitiveInfo,
     FileNormalizedNameInfo,
}

static if (NTDDI_VERSION >= NTDDI_WIN10_19H1)
{
    enum FILE_INFO_BY_HANDLE_CLASS :
