- langchain_core.utils.aiter.py_anext(iterator: ~typing.AsyncIterator[~langchain_core.utils.aiter.T], default: ~typing.Union[~langchain_core.utils.aiter.T, ~typing.Any] = <object object>) Awaitable[Union[T, None, Any]] [source]¶
Pure-Python implementation of anext() for testing purposes.
Closely matches the builtin anext() C implementation. Can be used to compare the built-in implementation of the inner coroutines machinery to C-implementation of __anext__() and send() or throw() on the returned generator.
