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.

My Personal Serverless Rust Developer Experience. It’s Better Than You Think
Without a solid build and debug experience, achieving a quality Serverless Rust Developer Experience would be next to impossible. For the next two sections of my setup, I leverage Cargo Lambda pretty hard. Cargo Lambda is a project that brings a subcommand into the Cargo ecosystem for building and testing Lambdas locally. I could also use it for deploying, but I stick to CDK for that.
-
Rust and Lambda
Tooling: I'll talk more about it below, but I love Cargo Lambda. I appreciate the fact that I can use SAM or CDK to build and deploy my code. And I've become a fan of using CodeWhisperer with VSCode to build my Rust Lambdas.

API Gateway, Lambda, DynamoDB and Rust
A few months back, the AWS SAM team released "beta" support for Rust using Cargo Lambda. Cargo is the crate/library manager for Rust and this additional subcommand brings in a lot of additional functionality. Per the Cargo Lambda team:

Consuming an SQS Event with Lambda and Rust
My journey through consuming an SQS Event with Lambda and Rust was enhanced when I embraced Cargo Lambda. Per the documentation:
-
Dynarust - no excuse for not using rust in AWS now - a DynamoDB ODM library that uses serde_json for mapping native rust structs to Dynamo items.
I have been using this code for a while in my rust projects, mainly for backend development deployed on AWS lambdas with https://www.cargo-lambda.info/.

Datadog APM
Has anyone experience with sending Traces from a Rust AWS Lambda (I've built mine with cargo-lambda) to Datadog APM? Sadly, there is nothing official yet and therefore also no examples I could try. Maybe some of you already have done it and could provide me with an example / tutorial?

Large Rust Lambda Package Size
Recently, I've been using cargo-lambda and cargo-lambda-cdk to deploy rust lambdas on AWS with the CDK.

Rust on Lambda Interest?
Hey op, have you used cargo-lambda? I haven't, but I wonder if it might help with whatever usability issues you've run into.

Rust on Lambda - Interest?
Have you tried https://www.cargo-lambda.info ? What are your thoughts on it? (not my project)

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).
