I was using Iced as a dependency, but wanted to tweak its source code for some reason, so I jumped into the folder where cargo downloads dependencies, and went into iced_wgpu 13.5 (I think that’s the version).

I could make a change, then run

cargo clean -p iced_wgpu && cargo check

in my other project for instant feedback, yet it took rust_analyzer at least 5 whole minutes to stop hallucinating.

Can I disable some functionality of rust_analyzer? I only use it for jump-to-definition, linting and syntax highlighting; I don’t even use autocomplete.

Setup:

  • Desktop that thermally throttles only when both the IGPU and the CPU are under full load, and is cool otherwise.

  • CPU: Intel I5-7500

  • RAM: 8 GiB DDR-4

  • Editor: NVIM v0.11.0-dev | Build type: RelWithDebInfo | LuaJIT 2.1.0-beta3 (I had the same issue with other versions as well).

TLDR

What can I disable in rust_analyzer to boost performance while maintaining jump-to-definition, linting and syntax-highlighting, or what can I do to boost rust_analyzer for big projects in general?

    Rather than modifying your dependencies in the cache directory (which is really not a good idea), consider cloning the repo directly. You can use a patch entry in your Cargo.toml to have all references to iced_wgpu point to your local modified copy.

      OP really needs to heed this advice. Modifying things in the cache will cause breakages that will confuse the hell out of you.
