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.

Hey Rustaceans! Got an easy question? Ask here (11/2021)!
My current end goal is to make a raw Rust binding for libopusenc (it's not the same as just opus, it implements some useful functionality on top of it, and as far as I know, no existing bindings exist for it yet, so I'm thinking of how I can do it).

Rust: Box Is a Unique Type
> The biggest annoying magic I found with respect to Box (and other std containers like Rc) is that they’re the only ones capable of storing fat dyn pointers. You can’t construct a hybrid_rc::Rc like you can with Box/Rc.
Anything can store fat dyn pointers, they're just like any other type in that regards.
Constructing them for a specific trait is easy and possible on stable (e.g. adding a `as_debug(MyBox) -> MyBox` method).
Making it possible to construct them for any trait is special to the built in pointers... on stable. On nightly with unstable features it's possible (and easy) to make any smart pointer type do this.
Code examples:

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...

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.
