Struct InstanceProxy

pub struct InstanceProxy { /* private fields */ }

Implementations

impl InstanceProxy

pub fn new(channel: AsyncChannel) -> Self

Create a new Proxy for examples.canvas.addlinemetered/Instance.

pub fn take_event_stream(&self) -> InstanceEventStream

Get a Stream of events from the remote end of the protocol.

Panics

Panics if the event stream was already taken.

pub fn add_line( &self, line: &[Point; 2], ) -> QueryResponseFut<(), DefaultFuchsiaResourceDialect>

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.
