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 do lifetimes need to be leaky?
No, you don't. Existential proof: mrustc ignores lifetimes. Just flat out simply ignores. It changes some corner-cases related to HRBT, yet rustc compiled by mrustc works (that's BTW mrustc exist: to bootsrap the rustc compiler).

I think C++ is still a desirable coding platform compared to Rust
Incidentally C++ is the only way to bootstrap rust without rust today.

Rust – Faster compilation with the parallel front-end in nightly
Well, there is mrustc[0], a Rust compiler that doesn't include a borrow-checker, so it's possible to compile (at least some versions of) Rust without a borrow checker, though it might not result in the most optimized code.
AFAIK there are some optimization like the infamous `noalias` optimization (which took several tries to get turned on[1]) that uses information established during borrow checking.
I'm also not sure what the relation with NLL (non-lexical lifetimes) is, where I would assume you would need at least a primitive borrow-checker to establish some information that the backend might be interested in. Then again, mrustc compiles Rust versions that have NLL features without a borrow-checker, so it's again probably more on the optimization side than being essential.

Forty years of GNU and the free software movement
> Maybe another memory safe language, but Rust has severe bootstrapping issues which is a hard sell for distros that care about source to binary transparency.
It is possible to bootstrap rustc from just GCC relatively easily, although it's a little bit time consuming.
You can use mrustc to bootstrap Rust 1.54: https://github.com/thepowersgang/mrustc
And from then you can go through each version all the way to the current 1.72. (Each new Rust version officially needs the previous one to compile.)

GCC 13 and the state of gccrs

Stop Comparing Rust to Old C++
There are three. The official one, mrustc (no borrow checker, but can essentially compile the official rustc) and GCC (can't really compile anything substantial yet). Only rustc is production-ready though.

Can I make it so that only the newest version of Rust gets installed?
That probably depends on what you mean by problematic. Having an ever increasing chain of dependencies isn’t the most desirable situation so there has been some work to trim the bootstrap chain. In 2018, when the blogpost I linked above was written, mrustc was used to bootstrap rust 1.19.0; now mrustc can bootstrap rust 1.54.0 so the chain to recent versions is much shorter than if all those intervening versions back through 1.19.0 needed to be built. https://github.com/thepowersgang/mrustc

Why is there no standard way of removing the mutability property from a reference?
Is perfectly valid Rust code. And there's reborrow, too.

Let's thank who have helped us in the Rust Community together!
I truly appreciate how much effort u/ehuss puts into maintaining The Rust Reference, considering that documenting stuff is not usually a fun task people want to do. Not to mention that ehuss is also the Cargo team lead, responsible for developing one of the most loved tools in Rust. ehuss's insightful knowledge always ensures that Cargo works without unexpected surprises.

Can someone please explain this to me? How does the compiler know about this for more advanced cases and when does it do this?
thank you this is definitely interesting and i need to read more. For anyone else, this is the thing I found about this issue when I looked it up. It's a github issue about how little documentation there is on the subject and that there should be more. Even the initial post has a lot of interesting details and links. Thanks for bringing it up although sorry it seems your comment went a bit over the heads of some redditors.
