AnyMsg equivalent in C++

Hi,

Is there any C++ alternative to rospy.AnyMsg? I need to forward a message in binary format so that I would like my node to subscribe to an unserialized version of the message, or something similar. The only solution I found so far is to create a custom adaptation as explained here in point 3.3, but this requires to customize the traits for every message type.

Thanks!

I saw it but for any reason I do not remember I thought it was not what I wanted.

The relay node in the topic_tools package uses ShapeShifter to forward messages without knowing their type: https://github.com/ros/ros_comm/blob/...
