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.

Was Rust Worth It?
Writing performance-sensitive code in C and calling it via interop used to be the way to go during .NET Framework days but since then has become a performance trap.
Especially for small methods, calling them through interop is a deoptimization because they cannot be inlined, and involve GC frame transition (which you can suppress) as well as an indirect jump and maybe interop stub unless you are statically linking the dependency into your AOT deployment. In case the arguments are not blittable to C - marshalling too.
It is also complicates the publishing process because you have to build both .NET and C parts and then package them together, considering the matrix of [win, linux, macos] x [x64, arm64], it turns into quite an unpleasant experience.
Instead, the recommended approach is just continuing to write C# code, except with pointer and/or ref based code. This is what CoreLib itself does for the most performance-sensitive bits[0]. Naturally, it intentionally looks ugly like in Rust, but you can easily fix it with a few extension methods[1].

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:)

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.
