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.

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.

The More You Gno: Gno.land Monthly Updates - 6
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).

How should I structure a medium sized crate?
For example, check out src/io/mod.rs or src/fs/mod.rs, which has a lot of re-exports. See also the standard library, e.g., src/sync/mod.rs.

Hyperbridge: Fast multi-producer, multi-consumer unbounded channel in Rust
Crossbeam isn't async[0]. It can multiplex with itself (via the `select!` macro), but not with anything else.
Why use this or Flume over the crossbeam multi-producer multi-consumer channel [1]? I thought crossbeam was well-regarded and pretty much the unofficial standard library for sync code.

Where can I read about how to write a safe API for unsafe code?
Shooting from the hip, crossbeam might be a good candidate for understanding the thread safety aspects of Rust. I kind of feel like this is probably "too big" of a project if you're just learning, but I can't think of something smaller off the top of my head that would be suitable.

Rust Tips and Tricks #PartOne
The crossbeam crate offers a powerful alternative to standard channels with support for the Select operation, timeouts, and more.
- This implementation is actually unsafe since we don't check if the index is in-bounds. But this is fine since this is only used internally.

Hey Rustaceans! Got a question? Ask here! (21/2022)!
The last option I can think of is using two threads (like above) and epoch GC instead of a lock (i.e. using crossbeam-epoch). But I don't have enough experience with this to say anything about it.
What are some alternatives?
async-std - Async version of the Rust standard library
rayon - Rayon: A data parallelism library for Rust
Rocket - A web framework for Rust.
hyper - An HTTP library for Rust
futures-rs - Zero-cost asynchronous programming in Rust
smol - A small and fast async runtime for Rust
actix-web - Actix Web is a powerful, pragmatic, and extremely fast web framework for Rust.
glommio - Glommio is a thread-per-core crate that makes writing highly parallel asynchronous applications in a thread-per-core architecture easier for rustaceans.
sqlx - 🧰 The Rust SQL Toolkit. An async, pure Rust SQL crate featuring compile-time checked queries without a DSL. Supports PostgreSQL, MySQL, and SQLite.
MIO - Metal I/O library for Rust.
bevy - A refreshingly simple data-driven game engine built in Rust
