The stream of frames must respect the protocol; if it doesn't, the behavior is undefined. Args: pause: Called when the buffer of frames goes above the high water mark; should pause reading from the network. resume: Called when the buffer of frames goes below the low water mark; should resume reading from the network.

Iterating the return value of :meth:`get_iter` asynchronously 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. Args: decode: :obj:`False` disables UTF-8 decoding of text frames and returns :class:`bytes`. :obj:`True` forces UTF-8 decoding of binary frames and returns :class:`str`. Raises: EOFError: If the stream of frames has ended. UnicodeDecodeError: If a text frame contains invalid UTF-8. ConcurrencyError: If two coroutines run :meth:`get` or :meth:`get_iter` concurrently. rdTNF)rWr rTr9rXrrmrjrkrr UTF8DecoderrYrfrlr)r#rYrhdecoders r$rqzAssembler.get_iters2   M"#KLL L# +//dk/::::::::EE%   #(D   |w&&%,)*C*C*C*C >\W,F  !mmG..UY77 7 7 7 7 7*    ) ! +//dk/::::::::E      <7**** !nnUZ;;;;;;;j    ) ! %s &AA rhrc|jrtd|j||dS)z Add ``frame`` to the next message.
