Implementations

impl InstanceSynchronousProxy

pub fn new(channel: Channel) -> Self

pub fn into_channel(self) -> Channel

pub fn wait_for_event( &self, deadline: MonotonicInstant, ) -> Result<InstanceEvent, Error>

Waits until an event arrives and returns it. It is safe for other threads to make concurrent requests while waiting for an event.

pub fn add_line( &self, line: &[Point; 2], ___deadline: MonotonicInstant, ) -> Result<(), Error>

Add a line to the canvas.

This method can be considered an improvement over the one-way case from a flow control perspective, as it is now much more difficult for a well-behaved client to “get ahead” of the server and overwhelm. This is because the client now waits for each request to be acked by the server before proceeding. This change represents a trade-off: we get much greater synchronization of message flow between the client and the server, at the cost of worse performance at the limit due to the extra wait imposed by each ack.
