Is it possible to write Rust on a low end system? (lemmy.today)

Rust analyzer and compilation are very slow. My system is heating up, running out of ram and disk space. I have 8 GB ram.

I use helix editor.

edit: thank you for all your suggestions. I am breaking up the project into smaller crates to see if that makes a difference.

I got the biggest improvements from zram and sccache. With zram my memory usage stays at 90% instead of fully running out when rust-analyzer starts.

My system has a midrange amd cpu with 6 cores. I have an ssd.

I think the issue has to do with procedural macros in maud. The project is about 1000 dependencies and 10k loc.

Combined with tailwind classes and a complex ui, the templates get bloated. I have to test this theory.

    Couldn't agree more here, 1k dependencies would take a while to build even on my 9950x3d if only due to linking.

    It seems to me like the the issue is the project is either too bloated, or large enough to justify a workstation build. Breaking it into smaller, independent parts would also help here.

    To me that's a very big project. Have you tried using fewer compilation threads? Maybe you need to sacrifice some speed to make it fit in memory and disk?
