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.

Why choose async/await over threads?
https://github.com/Xudong-Huang/may
The project has some serious restrictions and unsound footguns (e.g. around TLS), but otherwise it's usable enough. There are also a number of C/C++ libraries, but I can not comment on those.

Asynchronous Clean-Up (in Rust)
> e.g. Linux mutexes
You don't want to use blocking mutexes anyway with async.
> or Rust's Rc
This is only half true. The danger is that two `Rc` that point to the same data are in different threads. But it should be safe to move all of them at once from one thread to another, which is exactly the case if all the `Rc`s involved live inside a `Future`. The problem is that this is a non-local property that's hard to encode in the type system.
> By the way, if you wish to test uncolored async in Rust, you can find an implementation here: https://github.com/Xudong-Huang/may .
FYI that's known to be unsound due to thread locals. And more generally it doesn't seem to give much attention to safety (see for example how it allowed unsound scoped tasks, or the fact it allows doing unsafe operations in some of its macros due to wrong scoping of `unsafe` blocks).

What's the Benefit/Allure of Async/Await vs. CSP/Green Threads (and Other Concurrency Models)?
It seems that rust removed native green threads as against it's philosophy: https://stackoverflow.com/questions/29428318/why-did-rust-remove-the-green-threading-model-whats-the-disadvantage#29430403 but there are good CSP libraries e.g. https://github.com/Xudong-Huang/may and yet people really like e.g. Tokio for Async/Await (although it also has greenthreads!) What am I missing?

Async Rust Is A Bad Language
Can you admit that you failed in making it a pleasant experience to write async, especially for library authors? I don’t think it’s too late to admit failure and implement something like May https://github.com/Xudong-Huang/may

How Much Memory Do You Need to Run 1 Million Concurrent Tasks?
Your benchmark is comparing apples to oranges, you're benchmarking different things. If you wanted to compare a Rust solution to something like what Go does, you would need to use something like this library.

Can this new algorithm of Kotlin async be applied to Rust?
Yep. This is the best coroutine library right now https://github.com/Xudong-Huang/may
-
async fn calls can lead to surprising performance problems if they are nested too deeply
I am still intrigued by the stackful coroutine library, May https://github.com/Xudong-Huang/may. I would like to see how far this library can push the boundaries of being a higher level alternative to async

Goroutine equivalent
There is also "may" which attempts to be a Rust version of goroutines. I have not used it though, so can't comment on anything further about it.
-
Virtual Threads in Rust?
This library https://github.com/Xudong-Huang/may implement Stackful Coroutines in Rust which I believe is pretty close to what you're asking about. I believe it's a reasonably complete implementation, but it doesn't have much traction because most of the Rust ecosystem is using either async/await or native threads.

Working with Strings in Rust
I've never worked with C# so I need to look into that.
The one saving grace with Rust is if everyone decides to say "screw async" and just builds synchronous APIs, then we use something like [May](https://github.com/Xudong-Huang/may) for green threading.

Create a Custom GitHub Action in Rust
If you haven't dipped your touch-typing fingers into Rust yet, you really owe it to yourself. Rust is a modern programming language with features that make it suitable not only for systems programming -- its original purpose, but just about any other environment, too; there are frameworks that let your build web services, web applications including user interfaces, software for embedded devices, machine learning solutions, and of course, command-line tools. Since a custom GitHub Action is essentially a command-line tool that interacts with the system through files and environment variables, Rust is perfectly suited for that as well.

Why Does Windows Use Backslash as Path Separator?
Here's an example of someone citing a disagreement between CRT and shell32:
https://github.com/rust-lang/rust/issues/44650
This in addition to the Rust CVE mentioned elsewhere in the thread which was rooted in this issue:
https://blog.rust-lang.org/2024/04/09/cve-2024-24576.html
Here are some quick programs to test contrasting approaches. I don't have examples of inputs where they parse differently on hand right now, but I know they exist. This was also a problem that was frequently discussed internally when I worked at MSFT.

I hate Rust (programming language)
> instead of choosing a certain numbered version of the random library (if I remember correctly) I let cargo download the latest version which had a completely different API.
Yeah, they didn't follow the instructions and got burned. I still think that multiple things went wrong simultaneously for that experience. I wonder if more prevalent uses of `#[doc(alias = "name")]` being leveraged by https://github.com/rust-lang/rust/pull/120730 (which now that I check only accounts for methods and not functions, I should get on that!) so that when changing APIs around people at least get a slightly better experience.

Show HN: Fancy-ANSI – Small JavaScript library for converting ANSI to HTML
Recently did something similar in Rust but for generating SVGs. We've adopted it for snapshot testing of cargo and rustc's output. Don't have a good PR handy for showing Github's rendering of changes in the SVG (text, side-by-side, swiping) but https://github.com/rust-lang/rust/pull/121877/files has newly added SVGs.
To see what is supported, see the screenshot in the docs: https://docs.rs/anstyle-svg/latest/anstyle_svg/
