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.

New scalable, fault-tolerant, and efficient open-source MQTT broker
https://github.com/bytebeamio/rumqtt
Disclaimer: have not tried it myself. I was, however, considering using it to replace Mosquitto as a broker.
-
What MQTT crates for use in WASM are out there?
Other crates like https://crates.io/crates/paho-mqtt and https://github.com/bytebeamio/rumqtt are not available for browsers and do not compile to wasm.
- Announcing rumqttd v0.18.0: with improved performance and reduced binary size due to enhanced release profile, while featuring retained and will messages, will delay interval for MQTTv5 and other cool changes!
- Announcing rumqttd v0.17.0 with Shared Subscriptions and Subscription IDs adding up to better MQTTv5 support!
-
rumqttd now supports QoS2 and MQTT over websockets
Recently lot of new contributors showed interest, as well as contributed to rumqtt, so thank you so much everyone for your support <3 Feel free to discuss anything in comments, if you wish to contribute as well, you can look for `good-first-issues` ( or open new issues here )
- Rumqttd now supports MQTTv5 topic alias and message expiry
-
Announcing rumqttd v0.15.0 with MQTTv5 features like Topic Alias and Message Expiry
GitHub release - rumqttd-0.15.0
-
rumqttc 0.21.0 released with MQTT5 support
there is already an issue open for it: https://github.com/bytebeamio/rumqtt/issues/432. It is something that we would love to have, but not something in priority.
I wanted to let you know that rumqttc, a Rust MQTT client library, now supports several new features in MQTT 5 protocol. If you're not familiar with MQTT, it's a lightweight messaging protocol designed for IoT devices with limited resources.

Hey Rustaceans! Got a question? Ask here (15/2023)!
I know I should have asked this in their issues, but someone already did and didn't get a response. So I was not sure whether to create another issue, or comment in the same one (and not get a response as well?). So I decided to ask on Reddit first, thank you! https://github.com/bytebeamio/rumqtt/issues/598

Towards memory safety with ownership checks for C
You seem to have a preset opinion, and I'm not sure you are interested in re-evaluating it. So this is not written to change your mind.
I've developed production code in C, C++, Rust, and several other languages. And while like pretty much everything, there are situations where it's not a good fit, I find that the solutions tend to be the most robust and require the least post release debugging in Rust. That's my personal experience. It's not hard data. And yes occasionally it's annoying to please the compiler, and if there were no trait constraints or borrow rules, those instances would be easier. But way more often in my experience the compiler complained because my initial solution had problems I didn't realize before. So for me, these situations have been about going from building it the way I wanted to -> compiler tells me I didn't consider an edge case -> changing the implementation and or design to account for that edge case. Also using one example, where is Rust is notoriously hard and or un-ergonomic to use, and dismissing the entire language seems premature to me. For those that insist on learning Rust by implementing a linked list there is https://rust-unofficial.github.io/too-many-lists/.

Command Line Rust is a great book
Advent of Code was okay until I encounterd a problem that required a graph, tree or linked list to solve, where I hit a wall. Most coding exercises are similar--those requiring arrays and hashmaps and sets are okay, but complex data structures are a PITA. (There is an online course dedicated to linked lists in Rust but I couldn't grok it either). IMO you should simply skip problems that you can't solve with your current knowledge level and move on.

[Media] I'm comparing writing a double-linked list in C++ vs with Rust. The Rust implementation looks substantially more complex. Is this a bad example? (URL in the caption)
I feel obligated to point to the original cannon literature: https://rust-unofficial.github.io/too-many-lists/

Need review on my `remove()` implementation for singly linked lists
I started learning Rust and like how the compiler is fussy about things. My plan was to implement the data structures I knew, but I got stuck at the singly linked list's remove() method. I've read the book as well, but I have no clue how to simplify this further:

Factor is faster than Zig
My impression from the article is that Zig provides several different hashtables and not all of them are broken in this way.
This reminds me of Aria's comment in her Rust tutorial https://rust-unofficial.github.io/too-many-lists/ about failing to kill LinkedList. One philosophy (and the one Rust chose) for a stdlib is that this is only where things should live when they're so commonly needed that essentially everybody needs them either directly or to talk about. So, HashTable is needed by so much otherwise unrelated software that qualifies, BloomFilter, while it's real useful for some people, not so much. Aria cleaned out Rust's set of standard library containers before Rust 1.0, trying to keep only those most people would need. LinkedList isn't a good general purpose data structure, but, it was too popular and Aria was not able to remove it.
Having multiple hash tables feels like a win (they're optimized for different purposes) but may cost too much in terms of the necessary testing to ensure they all hit the quality you want.

Was Rust Worth It?
> Cyclic references can be dealt with runtime safety checks too - like Rc and Weak.
Indeed. Starting out with code sprinkled with Rc, Weak, RefCell, etc is perfectly fine and performance will probably not be worse than in any other safe languages. And if you do this, Rust is pretty close to those languages in ease of use for what are otherwise complex topics in Rust.
A good reference for different approaches is Learn Rust With Entirely Too Many Linked Lists https://rust-unofficial.github.io/too-many-lists/

How to start learning a systems language
Second, once you've finished something introductory like The Book, read Learning Rust With Entirely Too Many Linked Lists. It really helped me to understand what ownership and borrowing actually mean in practical terms. If you don't mind paying for learning materials, a lot of people recommend Programming Rust, Second Edition by Blandy, Orendorff, and Tindall as either a complement, follow-up, or alternative to The Book.
