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.

How to Lose Control of Your Shell
That's a valid Unix path, but rust's quoting does nothing to stop it: https://play.rust-lang.org/?version=stable&mode=debug&editio...

Borrow Checking Without Lifetimes
Self-referential structs work fine in Rust and always have.
https://play.rust-lang.org/?version=stable&mode=debug&editio...
The compiler will correctly prevent you from moving the value.
The other way to have a struct that starts out as non-self-referential and then becomes self-referential can be achieved with `unsafe` and `Pin::new_unchecked`, which is how `async {}` is handled.

Improving Interoperability Between Rust and C++
In rust as currently stands: https://play.rust-lang.org/?version=stable&mode=debug&editio...
On the other hand, both this wrapper and yours are counterproductive if the element size is dynamic (e.g. perhaps you're dealing with some nonsense like:)

New Linux glibc flaw lets attackers get root on major distros
Overflow checks turn into two's compliments' wrapping, but that's only considered acceptable because bounds checks are not turned off.

Atomics and Concurrency
I have no idea what you're talking about, but it sounds unnecessarily complicated and why I don't use Rust for any serious work.
This demonstrates the ABA problem in safe Rust: https://play.rust-lang.org/?version=stable&mode=debug&editio...
Substitute the sleep with a combination of doing computation/work and the OS thread scheduler, and you can see how the bug surfaces.

Hey Rustaceans! Got a question? Ask here (49/2023)!
Mystified about strings? Borrow checker have you in a headlock? Seek help here! There are no stupid questions, only docs that haven't been written yet. Please note that if you include code examples to e.g. show a compiler error or surprising result, linking a playground with the code will improve your chances of getting help quickly.

Hey Rustaceans! Got a question? Ask here (48/2023)!
If you have a StackOverflow account, consider asking it there instead! StackOverflow shows up much higher in search results, so having your question there also helps future Rust users (be sure to give it the "Rust" tag for maximum visibility). Note that this site is very interested in question quality. I've been asked to read a RFC I authored once. If you want your code reviewed or review other's code, there's a codereview stackexchange, too. If you need to test your code, maybe the Rust playground is for you.

Making Games in Go for Absolute Beginners
> I am the developer of Astral Divide, which is entirely written in Go: https://store.steampowered.com/app/2597060/Astral_Divide/
Your game looks great, congrats on your progress! I especially enjoyed how the zoom works when you're leaving/arrive planets, and the unique propulsion system (also, the anchor made me giggle!).
> lack of data structure packages
I tend to not need many, so I'd be curious if you can recall any structure in particular which you couldn't find? No biggie if not.
> package structure not suited for games
I'm not a game dev, but I've seen some larger games such as https://github.com/divVerent/aaaaxy/tree/main/internal (if you haven't played it before—do it!) which seem to be able to place everything into separate packages without issue, so perhaps there's something to gleam from their design?
> maps are random when iterated
Hash map iteration shouldn't be sorted in _any_ language (here's Rust, for example https://play.rust-lang.org/?version=stable&mode=debug&editio... (Python makes it _appear_ as if dicts are sorted hash maps, but that's only because it doesn't only use a hash table, but a vector as well (same as you'd have to do in Go))), otherwise it would cause both portability and security (https://github.com/golang/go/issues/2630) issues. You can use a b-tree (which was probably the data structure you wanted there) if you aren't willing to sort it yourself.
> modding options
If you don't care about unloading https://github.com/pkujhd/goloader
Go actually has one of the best WASM runtimes https://github.com/tetratelabs/wazero
It also has a bunch of libraries for embedding scripting languages https://awesome-go.com/embeddable-scripting-languages, with Tengo _probably_ being quickest https://github.com/d5/tengo
I'd _highly_ recommend Ebitengine in the future, as not only have there been multiple brilliant games using it, but it also has Switch/Android/iOS support, and you can find help with any issue whatsoever in their Discord. People have built 3D games with it, and Hajime is an absolute beast of a developer.

API Gateway, Lambda, DynamoDB and Rust
The AWS SDK makes use of the async capabilities in the Tokio library. So when you see async in front of a fn that function is capable of executing asynchronously.

The More You Gno: Gno.land Monthly Updates - 6
Petar is also looking at implementing concurrency the way it is in Go to have a fully functional virtual machine as it is in the spec. This would likely attract more external contributors to developing the VM. One advantage of Rust is that, with the concurrency model, there is already an extensive library called Tokio which he can use. Petar stresses that this isn’t easy, but he believes it’s achievable, at least as a research topic around determinism and concurrency.

Consuming an SQS Event with Lambda and Rust
Another thing to point out is that async is a thing in Rust. I'm not going to begin to dive into this paradigm in this article, but know it's handled by the awesome Tokio framework.

netcrab: a networking tool
So I started by using Tokio, a popular async runtime. The docs and samples helped me get a simple outbound TCP connection working. The Rust async book also had a lot of good explanations, both practical and digging into the details of what a runtime does.

Thread-per-Core
Regarding the quote:
> The Original Sin of Rust async programming is making it multi-threaded by default. If premature optimization is the root of all evil, this is the mother of all premature optimizations, and it curses all your code with the unholy Send + 'static, or worse yet Send + Sync + 'static, which just kills all the joy of actually writing Rust.
Agree about the melodramatic tone. I also don't think removing the Send + Sync really makes that big a difference. It's the 'static that bothers me the most. I want scoped concurrency. Something like <https://github.com/tokio-rs/tokio/issues/2596>.
Another thing I really hate about Rust async right now is the poor instrumentation. I'm having a production problem at work right now in which some tasks just get stuck. I wish I could do the equivalent of `gdb; thread apply all bt`. Looking forward to <https://github.com/tokio-rs/tokio/issues/5638> landing at least. It exists right now but is experimental and in my experience sometimes panics. I'm actually writing a PR today to at least use the experimental version on SIGTERM to see what's going on, on the theory that if it crashes oh well, we're shutting down anyway.
Neither of these complaints would be addressed by taking away work stealing. In fact, I could keep doing down my list, and taking away work stealing wouldn't really help with much of anything.

PHP-Tokio – Use any async Rust library from PHP
The PHP <-> Rust bindings are provided by https://github.com/Nicelocal/ext-php-rs/ (our fork of https://github.com/davidcole1340/ext-php-rs with a bunch of UX improvements :).
php-tokio's integrates the https://revolt.run event loop with the https://tokio.rs event loop; async functionality is provided by the two event loops, in combination with PHP fibers through revolt's suspension API (I could've directly used the PHP Fiber API to provide coroutine suspension, but it was a tad easier with revolt's suspension API (https://revolt.run/fibers), since it also handles the base case of suspension in the main fiber).

How should I structure a medium sized crate?
For example, check out src/io/mod.rs or src/fs/mod.rs, which has a lot of re-exports. See also the standard library, e.g., src/sync/mod.rs.
