Iterating the return value of :meth:`get_iter` yields a :class:`str` or :class:`bytes` for each frame in the message. The iterator must be fully consumed before calling :meth:`get_iter` or :meth:`get` again. Else, :exc:`ConcurrencyError` is raised. This method only makes sense for fragmented messages. If messages aren't fragmented, use :meth:`get` instead. Raises: EOFError: If the stream of frames has ended. ConcurrencyError: If two threads run :meth:`get` or :meth:`get_iter` concurrently. r!r"zqueue.SimpleQueue[Data | None]NTF)rrr&rrrrqueue SimpleQueuerrr)putr0r*r+rr-)rrchunkrrrget_iter|s8   zAssembler.get_iterr )framerc CsZ|j|jrtd|jr$td|jtkrrrrrr s &>AH) __future__rcodecsr1rtypingrr exceptionsrframesrrr r r __all__getincrementaldecoderr:r rrrrs
