I wrote something like this using reqwest for a Waveshare 7.5inch display. Also includes a dithering step so all that is needed is a web server serving an image. No conditional requests though but should be easy to add. It is fully statically compiled (even uses musl and rustls), runs on a very bare-bones Linux environment on a Raspberry. https://git.pixelspark.nl/pixelspark/sparkboard https://git.pixelspark.nl/pixelspark/sparkboard
