Need more details. I cannot reproduce this issue.

The following command runs fine:

cargo run --example real-time-routeviews-kafka-openbmp

We should probably replace the .unwrap() with some better error handling if it's for more than just example usages.

It is interesting. AFAIK, nothing has been changed on the computer. both are working now.

cargo run --example real-time-routeviews-kafka-openbmp

cargo build --examples ./real-time-routeviews-kafka-openbmp

Thanks for providing the details, and I'm glad that things are working now. I don't see anything that needs to be fixed here and the issues might have been the connectivity problem to remote kafka server. Let me know if you see any additional issues.
