轻量级的rpc

rpc::server srv(8080);

// Binding a lambda function to the name "add".
srv.bind("add", [](int a, int b) {
    return a + b;
});

// Run the server loop.
srv.run();

rpc::client client("127.0.0.1", 8080);      //支持端口重用，本机使用127.0.0.1不要使用0.0.0.0否则端口重用，数据会被127.0.0.1接收
// Calling a function with paramters and converting the result to int
auto result = client.call("add", 2, 3).as<int>();
