Hi Mycoliza! One of the authors of OpenTelemetry here. It would be great to see an OpenTelemetry implementation in Rust. If you're interested in bootstrapping a group to work on that, please let me know!
We absolutely want to integrate with OpenTelemetry, and I'd love to work with the OpenTelemetry community on that. We have an issue (https://github.com/tokio-rs/tracing/issues/89) tracking integration with distributed tracing systems --- it would be great to get input from OpenTelemetry folks if any of y'all are interested!
