Hi,

I'm currently evaluating the usage of rust in a dPDK application.

I wonder if there is other people who have done similar and would like to share experiences.

I have seen there is a couple of rust interface projects like capsule-rs.

Do you know of blockers why people seem to not be maintaining rust libraries like this one in the long term?

My research sofar has shown:

- rust codegen seems to be quite similar to C

- rust can generate autovectorized code

- ffi seems to be very low cost (similar to C++)

- allocation can be tricky given that there can be panics on allocations

I would love to hear your thoughts and reasoning.

Best regards,

Alexander Oh
