intellij-rust VS embassy

We’ll also consider the cases when IntelliJ IDEA licenses were primarily bought for Rust development with the IntelliJ Rust plugin and which options we can suggest to our users in these cases. Please stay tuned!

https://github.com/intellij-rust/intellij-rust/issues/10867#...

Last time I tried this, the plugin was incapable of actually showing compile errors in the project view and they said their false positive error rate was too high to enable it (https://github.com/intellij-rust/intellij-rust/pull/8373). That was a dealbreaker for me compared to VSCode.

Intellgi Rust is a good option.

Thank you all for the assist. Yep, not just a newbie issue which is surprising. :^) https://github.com/intellij-rust/intellij-rust/issues/10483

Warning about Unused_labels and implementation of MIR Now things are getting interesting

Agreed. Specifically, I've found the intellij rust plugin on top of Clion to be great.

figure out testing, you probably want to structure your app in a way that allows you to run it in testing (Zero to Production has a great approach to that). There are helpers for testing like sqlx::test but CLion Rust plugin doesn't support them yet, it breaks code analysis (afaik the fix is not released yet).

Any closer to getting error highlighting on files working properly (https://github.com/intellij-rust/intellij-rust/pull/8373)? That's a major benefit of rust-analyzer to me.

Could you please clarify whether the problem affects exactly local variables' values or function parameters' values? It is a known bug that the CLion's debugger cannot show function parameters' values on Windows: https://github.com/intellij-rust/intellij-rust/issues/6676. This is a major issue and we are working on it. But if you are facing such problems in any other scenarios, please let us know and share a problematic code snippet if possible

thanks. looked that up. for the curious: https://embassy.dev/

Running the Embassy RP2040 USB CDC ACM serial example takes about 5 seconds on a Pico.

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.

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?

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:

> 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!

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...
