dS )r z$Interface for write-only transports.Nc C s t �dS )a� Set 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.

r c @ s e Zd ZdZdS )r aS Interface 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.

� Z S )�_FlowControlMixinav All 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.
