Hi Engrin,
Terrific article! Thanks for writing it. I started working through it this morning, but am finding issues with the dependencies. In particular:
use opentelemetry::sdk::export::metrics::aggregation; use opentelemetry::sdk::metrics::{controllers, processors};
...are flagged by the compiler as not existing. I checked crates.io and "aggregation", "controllers", and "processors" don't exist.
Would be great if you could update your article.
Thanks,
