Specs

child_spec(options()) :: Supervisor.child_spec()

A function which can be used to embed an MLLP.Receiver under Elixir v1.5+ supervisors. Unlike start/1, start/2, or start/3 this function takes two additional options : ref and transport_opts. Note that if a ref option is not supplied a reference will be created for you using make_ref/0.

children = [{MLLP.Receiver, [
    ref: MyRef,
    port: 4090,
    dispatcher: MLLP.EchoDispatcher,
    packet_framer: MLLP.DefaultPacketFramer,
    transport_opts: %{num_acceptors: 25, max_connections: 20_000}
  ]}
]
Supervisor.init(children, strategy: :one_for_one)

See Options for details on required and optiomal parameters.
