Implementations

impl Server

pub fn start( config: Config, peer_listener: TcpListener, client_listener: TcpListener, )

Start listening to incoming connections from server peers and DHCP clients.

fn run_event_loop(&mut self, server_rx: &Receiver<Event>)

fn attempt_connect(&mut self)

fn become_coordinator(&mut self)

fn answer_handshake(&mut self, stream: TcpStream)

fn add_peer(&mut self, peer_id: Id, peer: Peer) -> Result<(), ()>

fn remove_peer(&mut self, peer_id: Id)

fn start_election(&mut self)

Send Message::Election to all server peers with higher ids than this server.

This function starts a timer thread which sleeps until the bully algorithm timeout expires. The timer triggers a Event::ElectionTimeout to the the server thread.

fn finish_election(&mut self)

Inspect current server role. Become leader and send Message::Coordinator to all peers if no event has reset the server role back to ElectionState::Follower.

fn handle_lease_request( &mut self, mac_address: MacAddr, tx: &Sender<LeaseOffer>, )

fn handle_confirm_request( &mut self, mac_address: MacAddr, ip: Ipv4Addr, tx: &Sender<bool>, )

fn handle_peer_message(&mut self, sender_id: Id, message: Message)

fn handle_election(&mut self, sender_id: Id)

fn handle_okay(&mut self, sender_id: Id)

fn handle_coordinator(&mut self, sender_id: Id, majority: bool)

fn handle_add_lease(&mut self, lease: Lease)

fn handle_set_pool(&mut self, pool: Ipv4Range)

fn handle_majority(&mut self, majority: bool)

Trait Implementations

impl Display for Server

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.
