I really like the idea of Rust. I just haven't seen anything convincing about support on the ESP32. Or really any MCU other than the STM32, which is hard AF to source these days.
here is esp32s3 rust hal if You have nor seen it already
https://github.com/esp-rs/esp-hal/tree/main/esp32s3-halmyself is targeting rp2040 = pico and are using "embassy" that has great async using a task executor,
"embassy" has some esp32 in pipeline as i understand is "work in progress"
