This repo is a tiny (< 70 lines of code) demonstration of displaying a constantly-updating image using the Rust crate egui. One thread updates the image, and another displays it. The crate uses triple_buffer to communicate between the threads. The image is just stored as an array of bytes.
I wrote this to explore testing image sensor hardware using Rust. With "hardware test software", sometimes you get a big 2D array of values and you just want to put some pixels on the screen, darnit.
I'm sharing this repo because I had difficulty figuring out how to get an array of values displayed as pixels on the screen using egui. I didn't find many good examples online. Hopefully this saves you a few minutes of searching. Good luck with whatever you're up to.
