class QgsVectorFileWriter : QgsFeatureSink
{
%Docstring(signature="appended")
A convenience class for writing vector layers to disk based formats
(e.g. Shapefiles, GeoPackage).

There are two possibilities how to use this class:

1. A static call to :py:class:`QgsVectorFileWriter`.writeAsVectorFormat(...) which saves the whole vector layer.
2. Create an instance of the class and issue calls to addFeature(...).
