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.

Async Rust Is A Bad Language
There's tracing-mutex that builds a dag of your locks when you acquire them and panics (at runtime) if it could deadlock: https://github.com/bertptrs/tracing-mutex
parking_lot has a deadlock detection feature for when you deadlock that iirc tells you what deadlocked (so you're not trying to figure it out with a debugger and a lot of time) https://amanieu.github.io/parking_lot/parking_lot/deadlock/i...
I also just found out about https://github.com/BurtonQin/lockbud which seems to detect deadlocks and a few other issues statically? (seems to require compiling your crate with the same version of rust as lockbud uses, which from the docs is an old 1.63 nightly build?)

Hey Rustaceans! Got a question? Ask here (23/2023)!
Hi, I'm looking for tools that can statically detect possible deadlocks in async fns. I'm aware of lockbud and cargo-check-deadlock, neither of which can analyse async code. Is there any tools that support this?

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.

What Rust feature are you waiting for?
I'd like to be able to write runtime agnostic async libs.

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].
