Observability Made Easy: Building a RESTful API with Actix Web and OpenTelemetry

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,
