[docs]def generate_uuid(*values: str | None, namespace: UUID = NAMESPACE_OID) -> str:
Convert input values to deterministic UUID string representation.
This function is only intended to generate a hash which used as an identifier, not for any security use.
Generates a UUID v5 (SHA-1 + Namespace) for each value provided,
and this UUID is used as the Namespace for the next element.
If only one non-None value is provided to the function, then the result of the function
would be the same as result of ``uuid.uuid5``.
All ``None`` values are replaced by NIL UUID. If it only one value is provided then return NIL UUID.
:param namespace: Initial namespace value to pass into the ``uuid.uuid5`` function.
if not values:
raise ValueError("Expected at least 1 argument")
if len(values) == 1 and values is None:
result = namespace
for item in values:
result = uuid5(result, item if item is not None else str(NIL_UUID))
