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.

Decrusting the tracing crate [video] by Jon Gjengset
The video description is as follows:
In this stream, we peel back the crust on the tracing crate — https://github.com/tokio-rs/tracing/ — and explore its interface, structure, and mechanisms. We talk about spans, events, their attributes and fields, and how to think about them in async code. We also dig into what subscribers are, how they pick up events, and how you can construct your own subscribers through the layer abstraction. For more details about tracing, see https://docs.rs/tracing/latest/tracing/.

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.

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.

How can I write a tracing subscriber that saves to a database?
I am using https://github.com/tokio-rs/tracing for logging purposes in my application. I would like to develop a feature wherein logs should be saved to a database table (via sea-orm). Something similar is this, but it does not solve my needs fully.

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)

Bundle frontend into axum binary using include_dir
There are some proposals on how to do it already such as https://github.com/tokio-rs/axum/issues/1698.

Prodzilla: From Zero to Prod with Rust and Shuttle
Moreover, I especially like where Rust is right now in the web space. It really feels like there’s a lot of smart people working on the next generation of web development tools - it feels like the place to be. There are a range of great open-source web dev tools that are just reaching critical levels of maturity. Axum, which I used to build Prodzilla, feels ready for out of the box web dev, and is crazy-performant, as I write about later. More recently available is Loco, a Rails-like framework for building web applications in Rust that's picking up steam. And in dev-tooling and hosting there’s Shuttle, a 1-line hosting solution for Rust backends.

You also get to specify the accepted HTTP method of the URL via axum::routing. To answer its name, modularity, Axum also supports nested routes as we'll see later in this series. Next is the layer, a method used to apply tower::Layer to all routes before it. This means that routes added after the layer method will not have such a layer applied to their requests. In our case, we used the layer to add tracing to all HTTP requests and responses to our routes. This is needed for proper logging. The tower_http::trace::TraceLayer can even be really customised.

Trying out Leptos: Fine-grained Reactive Framework for Rust
You have a couple of options for the underlying web framework to pair with Leptos: Axum or Actix. Axum seems to carry more favour currently, so we start with that. Assuming you already have Rust set up on your system:

Help required: Port kellnr from rocket.rs to axum
I’m the author of https://kellnr.io. When I started working on Kellnr three years ago, https://rocket.rs was “the web framework” to use. Unfortunately, the project seems dead. Before adding more functionality using an unmaintained framework, I want to port Kellnr to https://github.com/tokio-rs/axum.
