You are an expert in writing code in many different languages. Your goal is to perform code completion for the following code, keeping in mind the rest of the code and the file meta data.
    Metadata details:
    filename: full_mesh.rs
    path of file: ./repos/matchbox/matchbox_signaling/src/topologies
    
    the code of the file until where you have to start completion: use crate::{
    signaling_server::{
        error::{ClientRequestError, SignalingError},
        handlers::WsStateMeta,
    
    
    pub fn remove_peer(&mut self, peer_id: &PeerId) {
        let removed_peer = self
            .peers
            .lock()
            .as_mut()
            .unwrap()
            .remove(peer_id)
            .map(|sender| (*peer_id, sender));
        if let Some((peer_id, _sender)) = removed_peer {
            // Tell each connected peer about the disconnected peer.
            let event = Message::Text(JsonPeerEvent::PeerLeft(peer_id).to_string());
            // Safety: Lock must be scoped/dropped to ensure no deadlock with loop
            let peers = { self.peers.lock().unwrap().clone() };
            peers.keys().for_each(
                |peer_id| match self.try_send_to_peer(*peer_id, event.clone()) {
                    Ok(()) => info!("Sent peer remove to: {peer_id}"),
                    Err(e) => error!("Failure sending peer remove: {e:?}"),
                },
            );
        }
    }
