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.

Rust Tooling: 8 tools that will increase your productivity
tokio-console is a debugger for Rust async programs that use Tokio. To get started, add the console-subscriber crate to your project and add the following line which will initialise the subscriber and allow tokio-console to connect to it:
-
How to detect lock contention in rust?
You could try https://github.com/tokio-rs/console to debug and profile what happens with tokio tasks in your program.
-
Using Rust at a startup: A cautionary tale
The tokio-console CLI is a fun one. The console-subscriber supports shipping to a console server running elsewhere, apparently. That gives you a window into what's happening now.
-
Hey Rustaceans! Got a question? Ask here! (42/2022)!
Tokio console maybe? https://github.com/tokio-rs/console
-
use both of tracing-subscriber and tokio-soncole
If I add "console_subscriber::init()" line as https://github.com/tokio-rs/console recommends, tracing_subscriber cannot be initialized.

Any recommendations for profiling High performance rust code?
I'm building an HTTP load tester called pdc! I have run out of obvious (to me at least) places to look for performance gains. I'm achieving around 45,000 requests per second, per core. Right now I'm using hyper with a separate tokio runtime (in current thread mode) running on each core. So far having runtime on each core/NUMA node has really helped with cache coherency. Any recommendations for profiling beyond tokio console or tokio metrics (Convenient timing amirite!)?
-
Announcing `tracing` 0.1.30 with experimental `valuable`support!
It was just an accident and has been fixed https://github.com/tokio-rs/console/issues/270.
-
[Question] Is Tokio a poor fit for non-network related concurrent applications?
P.S. Tokio [now also has Tokio Console](https://github.com/tokio-rs/console) allowing you to conveniently troubleshoot your tasks if they are causing issues :)
-
How do I profile a Rust web application in production?
You can opt-in to async runtime such as tokio, and you can use tokio-rs/console for it's top-like metric
- `tokio::spawn` to handle `actix` message doesn't wait?

Unix-like OS in Rust inspired by xv6-riscv
My company, https://www.auxon.io. We created https://github.com/auxoncorp/ferros originally to enable a customer project early in the company's life cycle.
Some time later we had another customer interested in using it and having us add some features to it (e.g. some device drivers and a persistence layer utilizing https://docs.rs/tickv/latest/tickv/). It was becoming a massive pain in the neck to work out source code sharing agreements with them, so we decided to just open source it.
There are quite a number of things that we would do differently if we had to build it again, and at some point will likely do that work to revise it. The biggest one of those is root task synthesis. The other is to build and bring in facilities for running tasks that are compiled to WASM.

Writing an OS in Rust to run on RISC-V
When we add WASM support to https://github.com/auxoncorp/ferros it'll sorta be like what you're angling at there in your description.

My Fear of Commitment to the First CPU Core
We've built things on seL4 (https://github.com/auxoncorp/ferros). We like to joke that it's the most perfect piece of nearly featureless software ever made.
There's... A LOT... of work to do before seL4 is going to be anywhere near usability parity with something like Linux, unfortunately.
Rather than make a general purpose OS, we decided to use it more like a unikernel or "library OS" where you're trying to make a well defined kind of "appliance" image to deploy to specific hardware rather than try to fake being a POSIX-y shaped OS.

FerrOS: Rust-y unikernels on seL4
For what it's worth, here's FerrOS's repo as well as the underlying selfe repo

Tokio Console
That's basically what we did with https://github.com/auxoncorp/ferros, Bundle Rust programs together as tasks to run atop the formally verified seL4 microkernel.

Hubris – An OS from Oxide Computer
We also built a Rust framework called FerrOS (https://github.com/auxoncorp/ferros) atop the formally-verified seL4 microkernel.
It has a similar set of usage idioms to Hubris it looks like in terms of trying to setup as much as possible ahead of time to assemble what's kind of an application specific operating system where everything your use case needs is assembled at build-time as a bunch of communicating tasks running on seL4.
We recently added a concise little persistence interface that pulls in TicKV (https://docs.tockos.org/tickv/index.html) from the Tock project you referenced above, and some provisions are being added for some more dynamic task handling based on some asks from an automotive OEM.
-
Genode – Sculpt Operating System 21.10
We built a thing to enable combining Rust applications together to be hosted on the seL4 microkernel. The developer experience is more akin to that of something like an RTOS where the OS and your applications are built and deployed together. The whole premise of it is decidedly non-POSIX-like. The current point is for assembling software for use-case-specific/appliance computing, not general purpose computing. (https://github.com/auxoncorp/ferros)
We're looking both for contributors and also actively hiring for a couple engineering positions for the above and for or mainline product.

OSv Unikernel – Optimizing Guest OS to Run Stateless and Serverless Apps
I tried and failed to bring unikernels to my former work when I was at Visa. Specifically, LING.
At my current company, Auxon, we recently open sourced[1] some work we did a couple years back which is more or less an attempt at the basic foundations for blending the seL4 microkernel with fairly normal no_std Rust application development and assembling them all together to make a purpose built OS/application to deploy directly to hardware or within a VM. We have some work to do to keep building it up as a foundation for broader use, but we're looking into partnering with the seL4 Foundation (now under the Linux Foundation) to iterate on it further with some of our other mutual partners. The developer experience is much closer to that of developing for an RTOS than it is like typical general purpose computing development.
I'm of course biased, but I think there's a lot of room to innovate in the space of use case specific software stacks where the domain and constraints are well understood and too many degrees of freedom are actually a hindrance and a liability, not an advantage.

Open sourced: Easier builds and stronger types for seL4 with Rust
On top of that is ferros (no relation to to ferrous-systems), a higher-level userland of unreasonably strong types for compile-time resource tracking. No more discovering you need more memory, or capability slots or IPC rights at runtime. These types help you fit the right seL4 screw to the right seL4 screwdriver.
