Struct MessagePortSynchronousProxy

pub struct MessagePortSynchronousProxy { /* private fields */ }

Implementations

impl MessagePortSynchronousProxy

pub fn new(channel: Channel) -> Self

pub fn into_channel(self) -> Channel

pub fn wait_for_event( &self, deadline: MonotonicInstant, ) -> Result<MessagePortEvent, 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 post_message( &self, message: WebMessage, ___deadline: MonotonicInstant, ) -> Result<MessagePortPostMessageResult, Error>

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.

pub fn receive_message( &self, ___deadline: MonotonicInstant, ) -> Result<WebMessage, Error>

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.
