orjson.dumps()does not serializedataclasses.dataclassattributes that begin with a leading underscore, e.g.,_attr. This is because of the Python idiom that a leading underscores marks an attribute as "private."orjson.dumps()does not serializedataclasses.dataclassattributes that areInitVarorClassVarwhether using__slots__or not.
orjson.dumps()raises an exception if the object to be serialized is not given as a positional argument.orjson.dumps({})is intended and ok whileorjson.dumps(obj={})is an error.

directly to the returned
bytesobject.

default, in particular documenting the need to raise an exception if the type cannot be handled.
