exception

py4vasp.exception Module

Deals with the possible exceptions in py4vasp.

The design goal is that all foreseeable exceptions in py4vasp issue an exception of the Py4VaspException class. Any other kind of exception would indicate a bug in the code. If possible the part standard users interact with should not raise any exception, but should give advice on how to overcome the issue.
