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.

An Open Source Rust SNMP Simulator
The UdpFramed constructor must be supplied by an instance of a codec object, which implements the Encoder and Decoder Tokio crate traits. It’s used on top of the socket to handle frames. SnmpCodec is used to decode the received UDP socket data into a stream of SNMP messages, and to encode the SNMP messages into ASN.1 encoded UDP socket data. The SnmpCodec is a wrapper of rasn ASN.1 codec framework, which implements the Encoder and Decoder traits to encode and decode UDP frames. The decoder and encoder implementations leverage the rasn ASN.1 codec framework.

Fq: Jq for Binary Formats
Shameless plug, but you may be interested in my library (which is MIT/Apache-2.0) that offers decoding from BER/DER/CER all from a single model in code, there's no UPER/APER support at the moment, but it's coming in the next few months. :)

Rasn 0.4 — New Compile-Time Validation, SET and ANY support, new LDAP and PKIX crates, and more!
Hello everyone, I'm proud to announce the 0.4.0 of rasn! rasn is a #[no_std] codec framework for the ASN.1 data model and encoding rules. Allowing you to safely and easily parse ASN.1 data formats such as BER, CER, and DER in safe Rust. This release focused on rounding out the support for data types needed for more complicated specifications such as PKIX. If anyone has any questions about this release or rasn feel free to ask me here, or on the GitHub Discussions board.

ASN.1 & Serde: Which crate does the community recommend?
For ASN.1 I generally recommend rasn, which does not use serde since that is a poor fit for ASN.1. It went through an in-depth design phase and is currently the most complete and easy-to-use ASN.1 crate I'm aware of.

On Implementation of Distributed Protocols
Being able to control nondeterminism is particularly useful for testing and debugging. This allows creating reproducible test environments, as well as discrete-event simulation for faster-than-real-time simulation of time delays. For example, Cardano uses a simulation environment for the IO monad that closely follows core Haskell packages; Sui has a simulator based on madsim that provides an API-compatible replacement for the Tokio runtime and intercepts various POSIX API calls in order to enforce determinism. Both allow running the same code in production as in the simulator for testing.

API Gateway, Lambda, DynamoDB and Rust
The AWS SDK makes use of the async capabilities in the Tokio library. So when you see async in front of a fn that function is capable of executing asynchronously.

Petar is also looking at implementing concurrency the way it is in Go to have a fully functional virtual machine as it is in the spec. This would likely attract more external contributors to developing the VM. One advantage of Rust is that, with the concurrency model, there is already an extensive library called Tokio which he can use. Petar stresses that this isn’t easy, but he believes it’s achievable, at least as a research topic around determinism and concurrency.

Consuming an SQS Event with Lambda and Rust
Another thing to point out is that async is a thing in Rust. I'm not going to begin to dive into this paradigm in this article, but know it's handled by the awesome Tokio framework.

netcrab: a networking tool
So I started by using Tokio, a popular async runtime. The docs and samples helped me get a simple outbound TCP connection working. The Rust async book also had a lot of good explanations, both practical and digging into the details of what a runtime does.

Thread-per-Core
Regarding the quote:
> The Original Sin of Rust async programming is making it multi-threaded by default. If premature optimization is the root of all evil, this is the mother of all premature optimizations, and it curses all your code with the unholy Send + 'static, or worse yet Send + Sync + 'static, which just kills all the joy of actually writing Rust.
Agree about the melodramatic tone. I also don't think removing the Send + Sync really makes that big a difference. It's the 'static that bothers me the most. I want scoped concurrency. Something like <https://github.com/tokio-rs/tokio/issues/2596>.
Another thing I really hate about Rust async right now is the poor instrumentation. I'm having a production problem at work right now in which some tasks just get stuck. I wish I could do the equivalent of `gdb; thread apply all bt`. Looking forward to <https://github.com/tokio-rs/tokio/issues/5638> landing at least. It exists right now but is experimental and in my experience sometimes panics. I'm actually writing a PR today to at least use the experimental version on SIGTERM to see what's going on, on the theory that if it crashes oh well, we're shutting down anyway.
Neither of these complaints would be addressed by taking away work stealing. In fact, I could keep doing down my list, and taking away work stealing wouldn't really help with much of anything.

PHP-Tokio – Use any async Rust library from PHP
The PHP <-> Rust bindings are provided by https://github.com/Nicelocal/ext-php-rs/ (our fork of https://github.com/davidcole1340/ext-php-rs with a bunch of UX improvements :).
php-tokio's integrates the https://revolt.run event loop with the https://tokio.rs event loop; async functionality is provided by the two event loops, in combination with PHP fibers through revolt's suspension API (I could've directly used the PHP Fiber API to provide coroutine suspension, but it was a tad easier with revolt's suspension API (https://revolt.run/fibers), since it also handles the base case of suspension in the main fiber).
