buffer_diff_flags_t
===================================================================

.. currentmodule:: gi.repository.HarfBuzz


.. versionadded:: 1.5.0




.. class:: buffer_diff_flags_t
   :no-contents-entry:






Flags from comparing two :obj:`~gi.repository.HarfBuzz.buffer_t`'s.

Buffer with different :obj:`~gi.repository.HarfBuzz.buffer_content_type_t` cannot be meaningfully
compared in any further detail.

For buffers with differing length, the per-glyph comparison is not
attempted, though we do still scan reference buffer for dotted circle and
``.notdef`` glyphs.

If the buffers have the same length, we compare them glyph-by-glyph and
report which aspect(s) of the glyph info/position are different.
