What popular crates are available to build GUIs with widgets WITHOUT GPU? (programming.dev)

For some reason, it seems popular for GUI crates to use the GPU. I just want to make simple widgets, for like a calculator.

No fancy graphics. I want it quite lightweight.

For some reason, popular GUI crates love to do everything through a GPU, which bumps up the memory / cpu use significantly.

Slint fits the bill: We have a demo running on a line-buffer in a microcontroller with <300KiB of RAM. Framebuffers are of course supported as well, as is GPU-accelerated rendering.

Did you tick "Bot Account" by accident?

[–] hunger@programming.dev 5 points 2 years ago

I did tick that, since I saw text boxes and went "give me everything" without reading:-)

Fixed. Thank you for pointing this out.

You have much to learn Young Padawan. If you're wanting to make a desktop app in Rust it behooves one to avoid embedded web environments. For performance reasons of course.
