Behaviour for MQTT transport adapters.

Transport adapters handle the underlying network connections (TCP, TLS, WebSocket, etc.) and forward data to the MQTT protocol handler.

Implementing a Transport

defmodule MyTransport do
  @behaviour MqttX.Transport

  @impl true
  def start_link(handler, handler_opts, transport_opts) do
    # Start the transport server
  end

  @impl true
  def send(socket, data) do
    # Send data over the connection
  end

  @impl true
  def close(socket) do
    # Close the connection
  end

  @impl true
  def peername(socket) do
    # Get the peer address
  end
end
