I spent a weekend with Rust, a Raspi4, and our buddy GPT about six months ago. In that weekend I was able to get the Raspi controlling a OLED display via SPI with an SSD1306 controller. I thought it was a fairly clean port from C++, and GPT was well educated on how to use the RASPI SPI and I2C busses from Rust. I don't think I would be able to approach it on an ESP32 or AVR xMega or some other real microcontroller.
