%Docstring(signature="appended")
The :py:class:`QgsFieldMappingModel` holds mapping information for mapping from one set of :py:class:`QgsFields` to another,
for each set of "destination" fields an expression defines how to obtain the values of the
"destination" fields.
The model can be optionally set "editable" allowing to modify all the fields, by default only
the mapping expression is editable.

%Docstring
Constructs a QgsFieldMappingModel from a set of ``sourceFields``
and ``destinationFields``, initial values for the expressions can be
optionally specified through ``expressions`` which is a map from the original
field name to the corresponding expression. A ``parent`` object
can be also specified.

Sets a map of destination field name to :py:class:`QgsProperty` definition for field value.

Appends a new ``field`` to the model, with an optional ``expression``

Removes the field at ``index`` from the model, returns ``True`` on success

Moves down the field at ``index``

Moves up the field at ``index``

Sets the base expression context ``generator``, which will generate the expression
contexts for expression based widgets used by the model.
