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.

serde-numpy now supporting image formats!
Thanks to the zune-image library, serde-numpy is now supporting PNG and JPEG. Enabling faster io for neural net training loops and other image processing in python
-
Introducing zune-png: extremely fast PNG decoding in Rust
It has been extensively tested on 600,000 real world images, as well as fuzzed in various ways, and is now ready for production use!
-
Safety and Soundness in Rust
I might have misunderstood what you've written, but is there a reason you can't use https://github.com/etemesi254/zune-image as a JPEG decoder? It has minimal use of unsafe and is performant.

Announcing zune-jpeg: Rust's fastest JPEG decoder
It uses SIMD for colorspace conversion and IDCT, the code can be found here and here.
-
Introducing zune-inflate: The fastest Rust implementation of gzip/Zlib/DEFLATE
You can see a Github Action that zune-inflate uses here, it's mostly self-explanatory.

[Gitoxide in November]: high-speed diffing and pure-rust binary builds
I've just added a roundtrip fuzzer to the Rust translation of it so that we can start weeding out the bugs: https://github.com/etemesi254/zune-image/pull/13 Right now it finds some decoding failures in a few seconds.

Passing nothing is surprisingly difficult
Useful context on the Rust side is this issue [1]. It sounds like some of the author's concerns are addressed already.

Blog Post: Non-Send Futures When?
Is this captured by one of the known soundness conflicts? If not then should consider adding it to the list.
- Are crates like vcell and volatile cell still unsound?

Question: Are there things for Unsafe Rust learn from Zig?
There are some competing proposals for different memory models. Stacked borrows is the current proposal, but there are more work in the approproate WG.
-
Let's thank who have helped us in the Rust Community together!
Thank you /u/RalfJung for bringing formal methods to Rust, both through models like Stacked Borrows, by developing miri, and by working on unsafe-code-guidelines which aims to specify exactly what is and isn't allowed in unsafe code (surprisingly, it's an open question as 2023!)
- Questions about ownership rule
-
Noob Here: Why doesn't this work?
You could imagine some way to make this safe for example automatically convert &'short &'long mut T to &'short &'short T, but it's non-trivial to prove they are safe at all, not to mention ensuring this is correctly implemented in the compiler. If you're interested there's also a discussion on whether the opposite (& & T to & &mut T) is sound here.

When Zig is safer and faster than (unsafe) Rust
Agreed! MIRI is so good, it still feels like magic to me. It also comforts me that the Rust team takes improving unsafe semantics seriously, with the past Unsafe Code Guidelines WG and today's operational semantics team (t-opsem).

Safety and Soundness in Rust
I think there are some aspects of this rule that are still undecided. See for example:
- https://github.com/rust-lang/unsafe-code-guidelines/issues/8...
- https://github.com/rust-lang/miri/issues/2732

I wanna be a crab.
C is much better specified than unsafe Rust. Some things are just not worked out yet in Rust. This may sometimes even bite very experienced devs, such as this issue with Box's aliasing semantics, which tripped up the author of left-right.
