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.

Which async channel is best?
So this is actually better than true fairness (true fairness would lead to deadlock if a sender is forgotten). It is a pity that the there does not seem to be resources that document this design. There is this old thread where Carl provides some background, but I found it personally a bit hard to follow.

Async cancellation: a case study of pub-sub in mini-redis
Is this still true after it switched to using FuturesOrdered?
-
I don't really understand how I'm supposed to use async
Done.
-
Confused about how to use tokio to process a vector in parallel
You can use Streams, which are the async version of Iterators; They aren't stable yet, so you'll have to use a crate such as futures.

What crates would you consider essential?
futures
-
How to architect Rust code on Async/Await
For traits, like AsyncRead and AsyncWrite, go with the futures crate.

Async Rust in Practice: Performance, Pitfalls, Profiling
Here is the PR: https://github.com/rust-lang/futures-rs/pull/2551
Yield = wake the `waker_ref`. Avoiding the yield would be clone().wake().
That said, "poll immediately" isn't actually a thing nor was it ever a thing except in incorrect implementations.
-
What sort of mature, open-source libraries do you feel Rust should have but currently lacks?
Rust lacks an implementation of ReactiveX. futures/futures-signals seems to be the the ecosystem equivalent but I'm sure there'd be a lot of interest in an actual implementation.

Why isn't `rc::Weak<T>` marked `UnwindSafe`when T is `RefUnwindSafe`?
The opposite problem exists as well. Many types are actually unwind safe, but do not get the autotrait. In that case authors would have to manually declare them UnwindSafe. Because this is rarely done, having an API with a trait bound T: UnwindSafe is rarely viable in terms of ergonomics. It now obliges client code to wrap all calls to your API in AssertUnwindSafe which, if they use types from third party libraries, obliges them to assert this is fine. example

futures 0.3.9 released with big improvement in compile time
Also, we plan to give users more control in the future. See https://github.com/rust-lang/futures-rs/issues/2207, https://github.com/rust-lang/futures-rs/issues/2295, etc. for this
