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.

Is anyone using coroutines seriously?
I am using concurrencpp for my project. What I like about it is that it's basically a thread pool factory with coroutines. It allows for better structuring / organizing of multithreaded work. So for me the main advantage of coroutines is that the code looks easier to follow
- Concurrencpp – a C++20 library for coroutines and executors

Comparing asio to unifex
Equivalent concurrencpp code:
-
Do you think the current asynchronous models (executors, senders) are too complicated and really we just need channels and coroutines running on a thread pool?
I agree. I use concurrencpp for the exact use case you described - coroutines running on simple-to-understand-executors which return some asynchronous pipe for communication.
- concurrencpp version 0.1.6 has been released!

What happens if you co_await a std::future, and why is it a bad idea? - The Old New Thing
If you look at concurrencpp, you can control exactly where and how coroutines are resumed, using executors.

Collecting the best C++ practices
concurrencpp. Modern concurrency for C++. Tasks, executors, timers and C++20 coroutines to rule them all.

Just use a good third party library like concurrencpp .

Header-only C++14 quality thread pool
Hi, I am looking for a header-only C++14 (or lower) quality thread pool. Ideally, it would be similar to BS::thread_pool but in C++14. Most of them I find on GitHub are bloated (e.g. concurrencpp) or have many open Issues. Ideal usage would be similar to:
-
Good repos for beginners to browse that follow best modern C++ practices (including testing, static analysis etc...)
I use concurrencpp for my asynchronous code and the repo is written in modern cpp, with tests, sanitizers and what not.

Why choose async/await over threads?
thanks. looked that up. for the curious: https://embassy.dev/

Avoid Async Rust at All Cost
Async solves different problems, you can, for instance, have just a single-threaded CPU and still have a nice API if you have async-await. It might not be so cool at a higher level as Go's approach of channels and threads, but it's cool in embedded, read this:
https://github.com/embassy-rs/embassy?tab=readme-ov-file#rus...
"Rust's async/await allows for unprecedently easy and efficient multitasking in embedded systems. Tasks get transformed at compile time into state machines that get run cooperatively. It requires no dynamic memory allocation, and runs on a single stack, so no per-task stack size tuning is required. It obsoletes the need for a traditional RTOS with kernel context switching, and is faster and smaller than one!"
I'm just toying with Raspberry Pi Pico and it's pretty nice.
Go and Rust have different use cases, the async-await is nice at a low level.

Is anyone using coroutines seriously?
I have not yet dipped by toes in the Rust waters, but reading about the embassy project is actually what piqued my curiosity about using C++ coroutines in embedded. Are you familiar with the project or have you found it lacking?

The state of BLE and Rust (no_std)
I think I get the basics (shoutout to the Rust Embedded Working Group!), and I've started looking for the stack I'd be using. I think Embassy is really amazing, as well as the work of the ESP team -- hats off.

And this is how to do it using embassy, which is an async framework for embedded in rust:

The State of Async Rust
> not good for embedded
embassy begs to differ
https://embassy.dev/
async/await is really just a syntax for building state machines in a way that resembles regular code. It's compiled down to the same code that you would write by hand anyway (early on it had some bloat in state size but I think it's all fixed now).
And embedded has a lot of state machines!

Asynchronous Rust on Cortex-M Microcontrollers
You can run multiple executors at different interrupt priority levels (with multiple tasks per executor), which allows tasks on the higher priority executor to interrupt other tasks. Here's an example https://github.com/embassy-rs/embassy/blob/main/examples/nrf...
