Severing a connection

[simbleau]

In #283 I noticed something - We don't have a way to disconnect or sever a connection between two parties.

How can we go about this?

This is super useful. In a client/server architecture, the server may want to kick the client, for example!

I keep looking into this but it's not making sense how we could sever a connection.

My goal is for a peer to specifically stop listening, and end another peer's connection.

Ok so it was going to go in #283 but I'm just going to drop the code here so I can re-add it back later.

impl WebRtcChannel {
    /// Returns whether this channel is closed
    pub fn is_closed(&self) -> bool {
        self.tx.is_closed()
    }
}

impl<C: ChannelPlurality> WebRtcSocket<C> {
    /// Returns whether this socket is closed; this is considered closed as soon as any channel (not
    /// taken) is closed.
    pub fn is_closed(&self) -> bool {
        self.channels
            .iter()
            .filter_map(Option::as_ref)
            .any(|c| c.is_closed())
    }
}
