Support for nested messages?

[mcamurri]

Hi all,
thanks for making this project.

I would like to make a raspberry pi device communicate to a ROS pc without installing ROS on the rpi itself.

I know that ROS2 supports rpi OS but I'm sticking to ROS1 and I don't want to compile ROS1 from scratch on the rpi just to publish one single ROS message. I also don't want to install something like LCM and translate from LCM to ROS.

If I understand correctly, the cros library can scan a custom message definition (i.e. a *.msg file) and act as a publisher or subcriber for this message type.

My question is: does the library support nested message definitions, i.e. a custom message that refers inside itself to another custom message?

Thanks.
