ROS2 Rust Diagnostics Library

[imdexsam]

Does anyone know of an existing implementation of the ROS2 Diagnostics package for Rust?

If not (I'm assuming there isn't) is there a best practice to follow for creating rust implementations of common ROS2 packages?

Obviously there isn't a way to officially make Rust packages for the ROS2 buildfarm etc, but I'm wondering if there are any conventions people follow to help others find and contribute to ros2_rust-targeted packages.

I am started an implementation here: https://github.com/romainreignier/diagnostic_updater_rs
For now, DiagnosedPublisher is missing.
