I'm using a proc_macro, rust-analyzer makes cargo recompile every dependencies

Similar to this case.

Rust-Analyzer runs a slow cargo check every time I save, which takes about half a minute to complete.

This prevents me from running cargo run/build, as the lock file is being used. Additionally, because I'm using some macros, it forces my project to recompile every crate I'm using, making my workflow a horrible experience. When I want to change a single character, I have to wait up to 2 minutes to see the changes. This is just a testing file and not even the project itself, which will be much larger and I cannot imagine how this issue will scale.

What can I do to workaround this, my current setup deactivates cargo check on save, removing some ""quality of life"" that I had on other projects, nevertheless, this is almost the only way to do something, that or removing the extension.

Note

I tried using rust_analyzer (Pre-Release) to fix the issue, but it didn't help. I also tried other relevant solutions, but they didn't change the behavior.
