Latency

  let node = node::ipv4::machine(move |ip| {
    // do smth
  }).latency(Duration::from_secs(2), Duration::from_millis(100));

Packet loss

  let node = node::ipv4::machine(move |ip| {
    // do smth
  }).latency(Duration::from_secs(2), Duration::from_millis(100))
    .packet_loss(0.25, Duration::from_millis(500));

Features
