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.

Catch 22! Rust in Review
I believe the solution mentioned in rust-lang/wg-async is the way to go: Add traits like AsyncWrite, AsyncRead, Executor/Runtime to the std so that tokio/async-std can implement them.

Async Rust: What is a runtime? Here is how tokio works under the hood
This is a consequence of runtimes relying on global variables that their core future types are dependent on. Creating abstractions to solve this problem is one of the main goals of the the async working group [0].

How should I structure an async/await/futures program with multiple event sources and mutable state?
Provided the futures you're selecting over are cancellation safe the plain loop over select! should be fine. Multiple channels in particular are safe to select over - if you have futures that aren't cancellation safe, you can just wrap them up in a task on the end of a channel and then select on that.

Rust Weird Expressions
You might be interested in taking a look at and potentially participating in the "Async Vision Document"[1] which is an exercise the team is going through to collect feedback about the current state of the ecosystem and what the pain points are, as well as a way to lay doing what the desired future state of async Rust should be[2]. The process is happening, as you would expect, in the open and there's still time to influence it[3] if your concerns aren't yet addressed or even mentioned[4].

Building a shared vision for Async Rust
Thanks for the feedback. I posted this comment to a relevant github issue, fyi.

I want to share my latest hobby project, dbeel: A distributed thread-per-core nosql db written in rust
I used glommio as the async executor (instead of something like tokio), and it is wonderful. For people wondering whether it's "good enough" or to use C++ and seastar (as I have thought about a lot before starting this project), take the leap of faith, it's fast - both in terms of run time and to code.

The State of Async Rust
My understanding is you always need a runtime, somethings needs to drive the async flow. But there are others on the market, just not without the.. market domination... of tokio.
https://github.com/smol-rs/smol looks promising simply for being minimal
https://github.com/bytedance/monoio looks potentially easier to work with than tokio
https://github.com/DataDog/glommio is built around linux io_uring and seems somewhat promising for performance reasons.
I haven't played with any of these yet, because Tokio is unfortunately the path of least resistance. And a bit viral in how it's infected tings.

Learning Async Rust with Too Many Web Servers
I think you missed one which is based on io_uring [1].
In my benchmarks with a slightly tweaked version it was 2x faster than Nginx and and 30x faster than Python's SimpleHttpServer.

How much reason is there to be multi-threaded in the k8s environment
b) It's proven now e.g Seastar, Glommio that the fastest way to run a multi-threaded application is to have one instance with one thread pinned per CPU core. Then to have fibers/lightweight threads on top handling all of the asynchronous code. Your approach of lots of instances is the slowest so there will be a ton of unnecessary thread context-switching.
-
Why does Actix-web's handler not require Send?
I assume Tokio itself, see e.g monoio or glommio, but also Seastar for C++.

Use io_uring for network I/O
> Few of us have really figured out io_uring. But that doesn't mean it is slower.
seastar.io is a high level framework that I believe has "figured out" io_uring, with additional caveats the framework imposes (which is honestly freeing).

Is async runtime (Tokio) overhead significant for a "real-time" video stream server?
This use case is perfect for https://github.com/DataDog/glommio which is a thread-per-core runtime that is appropriate for latency sensitive code.

Blessed.rs – An unofficial guide to the Rust ecosystem
It's worth mentioning: Under "Async Executors", for "io_uring" there is only "Glommio"
I recently found out that ByteDance has a competitor library which supposedly has better performance:

Building a High-Performance DB Buffer Pool in Zig W\ Io_uring New Fixed-Buffers
FYI, Datadog has a Rust library for scheduling things to run thread-per-core with io_uring
It'd be really useful for DB use cases:
