Convert networkx graph to qgsvectorlayer in pyqgis

I'm converting to a QGIS processing plugin a python script that loads two spatial layers (nodes and edges), converts them to a graph using networkx and after doing some transformation converts back...

Thanks! The script I'm "translating" outputs a geopackage with two layers (nodes and edges), so the problem is not converting to a file but to an object of class qgsvectorlayer that is usually returned by qgis plugins. I know I could return a pointer to a temporary file (like SAGA algorithms) but I would prefer just returning the QGIS layer directly.

yep, I don't think there's any obvious way to transform and object from networkx to a qgis object.
