Member Enumeration Documentation

difference_type

enum llfio_v2_xxx::algorithm::comparison_summary::_lr::difference_type : uint8_t

The kind of difference.

Enumerator
entry	Entry name is here but not there.
entry_kind	Same entry name has different kind e.g. file vs directory.
content_metadata	Maximum extent or modified timestamp metadata is different.
noncontent_metadata	Non-content metadata (perms, non-modified timestamps etc) is different.
content	The content is different (if contents comparison enabled)
none	There is no difference.

      {
        entry,                //!< Entry name is here but not there
        entry_kind,           //!< Same entry name has different kind e.g. file vs directory
        content_metadata,     //!< Maximum extent or modified timestamp metadata is different
        noncontent_metadata,  //!< Non-content metadata (perms, non-modified timestamps etc) is different
        content,              //!< The content is different (if contents comparison enabled)
        none,                 //!< There is no difference
      };
