Stars - the number of stars that a project has on GitHub. Growth - month over month growth in stars.
Activity is a relative number indicating how actively a project is being developed. Recent commits have higher weight than older ones.
For example, an activity of 9.0 indicates that a project is amongst the top 10% of the most actively developed projects that we are tracking.

Vendor lock-in is in the small details
> What's been your biggest issues around ergonomics/amenities for OpenTelemetry?
I can't speak generally, but in the Rust ecosystem the various crates don't play well together. Here's one example: <https://github.com/tokio-rs/tracing/issues/2648> There are four crates involved (tracing-attributes, tracing-opentelemetry, opentelemetry, and opentelemetry-datadog) and none of them fit properly into any of the others.

Grimoire - A recipe management application.
The tracing (logging) mechanism in an asynchronous codebase (tracing).

How easy is it to swap out your async runtime?
Tracing is Tokio's alternative for async code.

Hey Rustaceans! Got a question? Ask here (27/2023)!
At a technical level, in Rust, both [tracing]https://crates.io/crates/tracing) and log are entire ecosystems (though for the latter at least there's also third party logging frameworks), and there's at least a bridge from log to tracing.

A locking war story
I've used the tracing infrastructure with tracing_flame to profile some hot paths in async code: https://github.com/tokio-rs/tracing/tree/master/tracing-flame

I was wrong about rust
Oh nice! IIRC when I checked, it was the Unicode tables that smashed the code size. I recently hit the same issue with the tracing crate, where a crate feature (for env var filtering) pulled in regex and my binary was suddenly 1MB bigger.

Debugging and profiling embedded applications.
I know about tools such as tracing, jaeger or tracy. While having a complete tracing could be a potential solution, these tools don't work with no_std.

Custom Axum Logging for Routes?
tracing by itself only outputs log data, you need to consume them in a subscriber, the tracing-subscriber crate exists for this. (example)

Trace Through a Kafka Cluster with Rust and OpenTelemetry
Let's look at some code. We have different ways to create spans in Rust. In this article, we focus on creating spans manually, not covering any abstractions such as tracing.

Hey Rustaceans! Got a question? Ask here (10/2023)!
Is there a standard crate / tool / practice for simplistic logging with Tokio? I presume it's tokio-tracing but there seems to be many bells and whistles when I'm looking for what amounts to essentially an async stderr with concurrent buffering.

What Are The Rust Crates You Use In Almost Every Project That They Are Practically An Extension of The Standard Library?

How easy is it to swap out your async runtime?
Depends on your logging crate. log does not depend on any async runtime.

Colorful logging with pizzazz!
It's a for-fun project that provides a configurable implementation for the log crate. This language and community is awesome, and I hope some of you get a kick out of this!

Rust playground on iOS
4) Another route that I tried is to develop a simple terminal app using SwiftUI with a Xcode project to build that app + link against a Rust library compiled for iOS with the actual logic. I used swift-bridge for this and it works really well, to the point where I have a custom logger that you can simply use the print stuff to SwiftUI from Rust using the log crate. Once I have a bit more time, I will probably try figuring out how to clean this up a bit more.
