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.

Yet another Web-Socket implementation in rust.
It passed all test of the autobahn testsuite And web-socket-benchmark show about 3x faster then tokio-tungstenite
-
Hey Rustaceans! Got a question? Ask here (7/2023)!
There are example files in the tokio-tungstenite crate called `autobahn-client.rs` and `autobahn-server.rs`. Why are they called autobahn? I googled and can't understand what autobahn is all about. Is it a websocket pattern? Or some protocol?

I'm using another crate that requires tls, specifically tokio-tungstenite, I'll try your suggestions later today once I get home

Hey Rustaceans! Got a question? Ask here (3/2023)!
Tokio-tungstenite - It looks like in this example, it's spamming the task thread with wakeup calls from all of the active connections. This design choice makes me doubt that this was well written in general.

Should i use ws-rs?
tokio-tungstenite is the more popular library. In frameworks, offhand Axum supports websockets (docs, example)

How would you refactor this code to use std's Mutex instead of Tokio's mutex
If you only have one task sending data to the sink, you probably don't need forward, as you can just write to the sink directly (you might not even need to split the stream in the first place, but i'm not sure about that). But often you want to write to the sink from different tasks (e.g. this example takes messages sent from one websocket connection, and broadcasts it onto every other connected websocket, so the sink for each websocket needs to be accessed by every other websocket handler task), and you can't do that with only the sink as you can't clone it. Either need to wrap it into a Mutex and clone that around the different tasks (and lock it every time you need to write to it, like OP did originally) or you can use forward to map the rx (receiver) of a channel to the sink, and clone the tx (sender) part of the channel for each task that wants to write to the sink. That way, you only have one task that is accessing the sink directly, so no issues with synchronization.
Yep, I assumed as much. in my example code the ws_stream is what you would get from tokio_tungstenite::accept_async. This example from the tungstenite repo shows using the forward method.

Hey Rustaceans! Got a question? Ask here! (30/2022)!
Has anyone worked with websockets before? Particularly with the tokio-tungstenite crate? I'm getting a Protocol(ResetWithoutClosingHandshake) error in my request. I send in some text, and i'm supposed to receive an audio file back.

What's the best production-grade websocket library in Rust?
tokio-tungstenite

help using async websocket using tokio-tungstenite
i based my code mostly on the client example from the tokio-tungstenite project: https://github.com/snapview/tokio-tungstenite/blob/master/examples/client.rs

Java 21 makes me like Java again
Yeah, it has nice funcional capabilities and libraries (like Arrow[0]).

Is it prudent to use Scala for anything new?
Last but not least, Scala is currently the language with one of the best effect systems in my opinion (https://zio.dev/). Kotlin for example has copied the approach with https://arrow-kt.io/ which I think is great actually. But when comparing Scala and Kotlin here, Scala wins by a large margin, it is a completely different world. It's like building a highly concurrent system in Erlang vs C.
Of course, if you don't want to learn things like union types, traits/typeclasses and effects (similar to async/await but more powerful) you will be annoyed by Scala. But once you learned them, you can never go back.

Struggling with software robustness with Kotlin
In my own code, I started to use explicit error handling. I'm currently experimenting with Result (from https://github.com/michaelbull/kotlin-result) and Raise (from https://arrow-kt.io/).

Hey Rustaceans! Got a question? Ask here (5/2023)!
Are there any more-or-less established functional crates in Rust (similar to Kotlin’s Arrow)?
-
What's the benefit of using Arrow with Kotlin?
I wonder how the community sees adding Arrow besides standard Kotlin language features. Is it something that's still considered useful or just redundant and causing more confusion?
-
If you HAD to work on a project that primarily used object-oriented design, what functional programming patterns (if any) would you keep in your tool box?
Kotlin’s really nice, and even better with http://arrow-kt.io

Kotlin for JavaScript
This is very exciting, I have wanted to try Kotlin for quite some time and one of the biggest reasons has been few libraries such as arrow-kt[1].
> Kotlin/JS provides the ability to transpile your Kotlin code, the Kotlin standard library, and any compatible dependencies to JavaScript.
What does it means "compatible dependencies"?
