ddZdS)rz$Interface for write-only transports.rNcCstdS)aSet the high- and low-water limits for write flow control.

        These two values control when to call the protocol's
        pause_writing() and resume_writing() methods.  If specified,
        the low-water limit must be less than or equal to the
        high-water limit.  Neither value can be negative.

        The defaults are implementation-specific.  If only the
        high-water limit is given, the low-water limit defaults to an
        implementation-specific value less than or equal to the
        high-water limit.  Setting high to zero forces low to zero as
        well, and causes pause_writing() to be called whenever the
        buffer becomes non-empty.  Setting low to zero causes
        resume_writing() to be called only once the buffer is empty.
        Use of zero for either limit is generally sub-optimal as it
        reduces opportunities for doing I/O and computation
        concurrently.

		rc@seZdZdZdZdS)raSInterface representing a bidirectional transport.

    There may be several implementations, but typically, the user does
    not implement new transports; rather, the platform provides some
    useful transports that are implemented using the platform's best
    practices.

    The user never instantiates a transport directly; they call a
    utility function, passing it a protocol factory and other
    information necessary to create the transport and protocol.  (E.g.
    EventLoop.create_connection() or EventLoop.create_server().)

    The utility function will asynchronously create a transport and a
    protocol and hook them up by calling the protocol's
    connection_made() method, passing it the transport.

    The implementation here raises NotImplemented for every method
    except writelines(), which calls write() in a loop.

ddZZS)_FlowControlMixinavAll the logic for (write) flow control in a mix-in base class.

    The subclass must implement get_write_buffer_size().  It must call
    _maybe_pause_protocol() whenever the write buffer size increases,
    and _maybe_resume_protocol() whenever it decreases.  It may also
    override set_write_buffer_limits() (e.g. to specify different
    defaults).

    The subclass constructor must call super().__init__(extra).  This
    will call set_write_buffer_limits().

    The user may call set_write_buffer_limits() and
    get_write_buffer_size(), and their protocol's pause_writing() and
    resume_writing() may be called.
