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.

RFC: Rust Has Provenance
Provenance is a dynamic property of pointer values. The actual underlying rules that a program must follow, even when using raw pointers and `unsafe`, are written in terms of provenance. Miri (https://github.com/rust-lang/miri) represents provenance as an actual value stored alongside each pointer's address, so it can check for violations of these rules.
Lifetimes are a static approximation of provenance. They are erased after being validated by the borrow checker, and do not exist in Miri or have any impact on what transformations the optimizer may perform. In other words, the provenance rules allow a superset of what the borrow checker allows.

I've incidentally created one of the fastest bounded MPSC queue
Actually, I've done more advanced tests with MIRI (see https://github.com/rust-lang/miri/issues/2920 for example) which allowed me to fix some issues. I've also made the code compatible with loom, but I didn't found the time yet to write and execute loom tests. That's on the TODO-list, and I need to track it with an issue too.

Interested in "secure programming languages", both theory and practice but mostly practice, where do I start?
He is one of the big brains behind Miri, which is a interpreter that runs on the MIR (compiler representation between human code and asm/machine code) and detects undefined behavior. Super useful tool for language safety, pretty interesting on its own.
-
Formal verification for unsafe code?
I would also run your tests in Miri (https://github.com/rust-lang/miri) to try to cover more bases.

Ouroboros is also unsound
You can run miri and it will tell you if the given run triggered any undefined behavior. It will not analyze it for every possible use of the code, but checking for the presence of this specific issue using it should be fairly simple.

From Stacks to Trees: A new aliasing model for Rust
If you do encounter a piece of code on which TB performs much worse than SB, do submit it as an issue! There was one recently and we massively improved TB performance on this case by improving garbage collection.

My Rust program (Well, game) is leaking memory, 4MB/s.
Have you tried adding miri checks to see specific warnings it suggests? It should have some memory leak checks aswell. https://github.com/rust-lang/miri

What would be your programming language of choice to implement a JIT compiler ?
Depends on what you mean by "better experience". What the article doesn't mention is the fact that you can still run into undefined behavior (including pointer aliasing) in C/C++/Zig and have your programs exhibit unexplainable weirdness, but you won't get any help from the language/compiler to figure out where it's coming from. In Rust you just run MIRI which tells you exactly where you have undefined behavior as long as you have at least one test which exercises the affected code path.

[Media] I'm comparing writing a double-linked list in C++ vs with Rust. The Rust implementation looks substantially more complex. Is this a bad example? (URL in the caption)
itโs even written by the same person that wrote the Nomicon (the guide to the dark arts of unsafe)

Rust books to read
If you want to dive deeper you can always have other options but now there are concrete cases, if you want to do low level thing https://doc.rust-lang.org/nomicon/ while if you want multi thread/concurrency stuff https://marabos.nl/atomics/ . There are many many books so you will have to point yourself to what you want

Unsafe Rust
Nice video! Glad I could help out. This stuff is hard, and I'm still learning a lot about it myself even years later. The Rustonomicon is a great read if you haven't already.
-
Stepping up the YAML engineer game
Have you got a moment to read through the good book , after reading through this perhaps try the Rustonomicon.
- Questions about ownership rule
-
How to write deserializer for custom binary protocol?
However, this is a wide topic out of scope for a Reddit comment, so maybe just read the Rustonomicon. It explains everything about data handling in Rust.

Performance critical ML: How viable is Rust as an alternative to C++
The ownership model & borrow checker makes rust a bit of an awkward language in which to write complex data structures like trees and graphs. It can be done - since you can always use raw pointers & unsafe code when you absolutely need to to treat rust like C. But the language fights you, and the community can get a bit moralistic about this sort of thing. The rust nomicon is a fantastic resource for learning the limits of the borrow checker, and where and how to use unsafe code correctly. You will need unsafe less than you think you will, but sometimes you will have no choice.

Sudo and Su Being Rewritten in Rust for Memory Safety
That's a really good point that I feel like isn't talked about enough. Unsafe rust is a lot harder to write correctly than bog standard C, because you have to uphold the invariants to avoid undefined behavior (1). It's why there's a whole ebook about it (2).
That doesn't mean it's impossible to write correct unsafe code, it's just not as obvious as "trust me bro I know better than borrowck." You can't actually elide the invariants Rust upholds, you just have to take over from the compiler when it can't prove them.

C++ to Rust Books?
If you are interested in the theoretical stuff that doesn't have much overlap with C++, give the Nomicon a try, or even Learn Rust the Dangerous Way.

How can I use rust libraries in zig/C
There's also cbindgen for automating the generation of C headers once you've got your code in the right shape and you'll also want to read the Rustonomicon.
What are some alternatives?
