Some type supports are not specific to the rmw. impl and are being used by multiple different ones (e.g. [rosidl_typesupport_introspection_cpp](https://github.com/ros2/rosidl/tree/master/rosidl_typesupport_introspection_cpp)). Others are specific to one rmw implementation and defining between the ROS types and the DDS types using the vendor specific API (e.g. [rosidl_typesupport_connext_cpp](https://github.com/ros2/rmw_connext/tree/master/rosidl_typesupport_connext_cpp)). --- [Visit Topic](https://discourse.ros.org/t/ros-2-type-support-functions/3495/2) or reply to this email to respond.
