Trait SignalVmbusChannel

pub trait SignalVmbusChannel: Send + Sync {
    // Required methods
    fn signal_remote(&self);
    fn poll_for_signal(
        &self,
        cx: &mut Context<'_>,
    ) -> Poll<Result<(), ChannelClosed>>;
}

An object to use to communicate notifications with the remote endpoint of a vmbus channel.

When dropped, this may (or may not) signal to the remote endpoint that the channel is being closed.

Required Methods

fn signal_remote(&self)

Signals the remote endpoint that there is work to do: either the outgoing ring buffer has transitioned from empty to non-empty, or the incoming ring buffer now has enough space for the remote endpoint’s pending send.

fn poll_for_signal( &self, cx: &mut Context<'_>, ) -> Poll<Result<(), ChannelClosed>>

Poll the channel for a ring buffer signal or for being closed.

If the remote endpoint has closed the channel, then this can return ChannelClosed.
