Recently the Rust compiler gain support for AVR targets like the atmega32u4 in the UDOO Bolt. I created a Rust program for the atmega32u4 to display text received from a USB serial port on an I2C OLED display. https://github.com/mogenson/udoo-display
Keep in mind that developing for low-level platforms like AVR microcontrollers using Rust may involve working with unsafe code and manually manipulating hardware registers. Be sure to consult the documentation for the AVR microcontroller, the OLED display module, and the Rust crates you're using for detailed instructions and examples specific to your setup.
