pub struct MessagePortProxy { /* private fields */ }

Implementations§

source§

impl MessagePortProxy

source

pub fn new(channel: AsyncChannel) -> Self

Create a new Proxy for fuchsia.web/MessagePort.

source

pub fn take_event_stream(&self) -> MessagePortEventStream

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

§Panics

Panics if the event stream was already taken.

source

pub fn post_message( &self, message: WebMessage ) -> QueryResponseFut<MessagePortPostMessageResult>

Sends a WebMessage to the peer. These are processed in order, one at a time. It is not necessary for the caller to wait for the completion callback before calling [MessagePort.PostMessage] again.

If an error occurred, the FrameError will be set to one of these value:

  • BUFFER_NOT_UTF8: The script in message’s data property is not UTF-8 encoded.
  • NO_DATA_IN_MESSAGE: The data property is missing in message.
source

pub fn receive_message(&self) -> QueryResponseFut<WebMessage>

Asynchronously reads the next message from the channel. The client should invoke the callback when it is ready to process another message. Unreceived messages are buffered on the sender’s side and bounded by its available resources.
