Detailed Description

UDP server that runs the handshake, tracks connections and dispatches messages.

Network I/O runs on a dedicated thread, so every callback is invoked from that thread and the caller must synchronize any data it shares with the game loop.

MessageCallback

using NetworkServer::MessageCallback

Initial value:

 
      std::function<void(std::uint32_t connectionId, MessageId type,
                         const std::vector<std::uint8_t> &payload)>

Callback receiving a message that the network layer does not handle.
