This causes the attributes contained within the given ``feature`` to be rearranged (or in
some cases dropped) in order to match the fields and order indicated by ``fields``.
The exact behavior depends on whether or not ``feature`` has a valid fields container
set (see QgsFeature.fields()). If a fields container is set, then the names of the
feature's fields are matched to ``fields``. In this case attributes from ``feature``
will be rearranged or dropped in order to match the field names from ``fields``.
If the ``feature`` does not have a valid fields container set, then the feature's attributes
are simply truncated to match the number of fields present in ``fields`` (or if
less attributes are present in ``feature`` than in ``fields``, the feature's attributes
are padded with NULL values to match the required length).
