is_conflict

Function: warmhub.is_conflict

is_conflict(error: object)

Whether error is a lost race: re-read, re-apply, retry.

True for CONFLICT and PRECONDITION_FAILED. When the backend sent structured details, expected_version and current_version say which versions disagreed:

try:
    repo.batch().revise(name=n, data=d, expected_version=v).commit()
except WarmHubError as err:
    if not is_conflict(err):
        raise
    current = err.current_version   # None if the backend sent no details
    ...
