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.

Rust has been forked to the Crab Language
This fork promises "All of the memory-safe features you love, now with 100% less bureaucracy!" Compelling, until you realise that all the commits are auto-merges of rust-lang/rust's main branch. Which means the same teams doing the same work, under a different name.
Rust is experiencing growing pains because they're still figuring out a governance structure that works for everyone. They want to simultaneously keep the current structure of bottom up development where each team (compiler, lang, crates.io, cargo) has the autonomy to make decisions for themselves, but the project as a whole can speak can come to a consensus and speak with a single voice. That's what this RFC tries to capture (https://github.com/rust-lang/rfc-leadership-council/blob/mai...). But the project isn't there yet, and is making these frustrating missteps in the interim. The lack of transparency into these missteps manifests as "bureaucracy" to outsiders like us.
If Crab lang actually attracted people doing the real work of development, they would have the exact same "bureaucracy" as teams tried to figure out how to build consensus and speak with one voice. The fact that they don't have bureaucracy is a direct consequence of them not doing any work right now. None of the people involved in regular Rust work, as far as I can tell, so they might not be aware of this.
Lastly, I want to note that the top comment in this thread is blaming the Foundation, which is simply bizarre. The Foundation very explicitly tries to stay hands off on technical decisions and does not interfere in how the teams organise themselves. You may disagree with that, but it's an inaccurate characterisation.

Rust: Box Is a Unique Type
If you have an object that's !Unpin, then Miri will not apply uniqueness rules to anything containing it [0], including boxes and &mut references. (In the example code, replacing the PhantomPinned with a () will make Miri complain again.) This is considered a temporary (if long-lived) measure to allow async executors to manipulate pinned futures without invalidating all their references and whatnot. Thus, it might be seen as undetected UB, in lieu of a permanent solution.

Fivefold Slower Compared to Go? Optimizing Rust's Protobuf Decoding Performance
That would be true if you used `Vec::clear` too, it doesn't allocate a new vector. My point was that you still end up running Drop implementations with RepeatedField, just not all at once. See 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.

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:)

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.
