What is the Rust used for here? Do you manually write x,y pixels to these devices?

Can you use another program to rasterize a two tone bitmap image with the appropriate dimensions and then pass it to the display controller without needing to write any software?

Rust runs on the esp32 to send the data to the display, and is used on the server side to generate the image that is then served up to the esp32 to send to the display.

There is minimal software on the e-ink display side… it connects to wifi, fetches the image, and sends it to the display.
