A key in the "unix" namespace for getting the mode of the file (e.g. whether the file is a regular file, symlink, etc). See the documentation for `lstat()`: this attribute is equivalent to the st_mode member of struct stat, and includes both the file type and permissions. This attribute is only available for UNIX file systems. Corresponding GFileAttributeType is G_FILE_ATTRIBUTE_TYPE_UINT32.

enum FILE_ATTRIBUTE_UNIX_MODE = "unix::mode";
