Detailed Description

Stand-in for `rospy.AnyMsg`.

Message class to use for subscribing to any topic regardless of type. Incoming messages are not deserialized. Instead, the raw serialized data can be accessed via the buff property.

Caveat in ROS2: subscription will be made with the first available published type on this topic, creation will fail if no publisher is available. Will not provide messages of different types.
