Signature

class NodeConflict

Documentation

Raised when a node cannot be created because one with the id already exists.

Reserved for future use by explicit-id insertion paths; base schema saves generate fresh ULIDs and therefore never conflict.

Example:

>>> from mnemosine import NodeConflict
>>> raise NodeConflict("duplicate id")
Traceback (most recent call last):
...
mnemosine.exceptions.NodeConflict: duplicate id
