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.

Production grade databases in Rust
Also, not to be too bad about a reputation fallacy, but I found the author to be flippant and disrespectful when good-faith unsoundness was pointed out in his crates: https://github.com/spacejam/rio/issues/30

Linear Types One-Pager
In my previous post on linear types I spent quite a bit of time motivating linear types. For example the ergonomic rio io_uring library could be made sound if it could guarantee destructors are run. Or performing FFI with async C++ could be made more efficient if it could rely directly on destructors rather than having to involve an intermediate runtime for each call.

The Stigma Around Unsafe
It's like cargo should have a way to mark a dependency as unsafe. That way, you could have a safe mmap crate as an unsafe dependency. Or something like rio which is deliberately unsound (but is fine if you abide by its rules through the entirety of the program)

Anyone using io_uring?
for completeness there is also rio, but:
-
Comparing the Rust uring libraries (tokio-uring, glommio, rio, ringbahn)
rio still has known soundness issues– its Completion futures block the thread when dropped (!!!), and can allow for use-after-free bugs if leaked. See https://github.com/spacejam/rio/issues/30 for details.

Tokio, the async runtime for Rust, hits 1.0
The author of sled[1], an embedded database in Rust which has a number of promising features, has also written parts of rio[2], an underlying pure Rust io_uring library, which is intended to become the core write path for sled. rio has support for files but also has a demo for TCP (on Linux 5.5 and later) and O_DIRECT.
I tested rio recently as I had a Brilliant but Bad Idea™ involving file access and was pleasantly surprised by the API, as I have been with sled's.
I'm excited for the experimentation in the Rust ecosystem and for such low level crates to handle the complex io_uring tasks (relatively) safely!

Show /r/Rust: keepcalm (and call Clone), a simpler way to manage synchronization
I’m making use of this in a few of my projects (https://github.com/progscrape/progscrape/ and https://github.com/mmastrac/stylus/ so far) and I’m quite happy with the quality-of-life improvements. Happy to share it with the community-at-large and solicit ideas/feedback. PRs welcome!

Dashy – A self-hosted homepage for your homelab
This is pretty cool.
If you don't need all the bells and whistles from this (including auth!), I built a homelab status page server that's designed for someone like me that just wants to whip up an SVG in draw.io or diagrams.net and make it semi-interactive:

I use it to keep tabs on a small fleet of equipment and get at-a-glance status for everything.

Tokio, the async runtime for Rust, hits 1.0
I always get a weird vibe from async-std. I respect the people working on it, but it feels like it's trying to boil the ocean.
I'd be very interested in hearing other opinions, as my Rust project [1] is currently stuck on an older version of Tokio while I wait for deps to update.
