I'd disagree. Using something like Embassy is pretty pleasant for embedded development, less worries than C. The only issue is maturity.

There were sufficient crates to write a ssh server for a rp2040 (mostly out of curiosity) using what's available in no_std.

Do you have that example posted anywhere? I'm curious to see it. Also, any support for the Wifi and/or Bluetooth on Pi Pico W from Rust?

https://github.com/mkj/sunset/tree/main/embassy/demos/picow is a wifi-ssh to serial impl for a rp2040. I've got it plugged into my home server's serial port. It's using cyw43 for wifi also from Embassy - dirbaio is prolific! There's some WIP in Embassy for bluetooth.

That repo has a few crates depending on each other - sunset is the toplevel ssh, sunset-embassy adds no_std async, then the async dir has std rust, with a commandline ssh client in the examples dir.

First time I'm hearing about Embassy. Looks like things have progressed since last time I tried deploying rust on an stm32.
