Description

Is there a way to exclude a single crate from analysis?

I've got a dependency in my project that takes too much time to analyze (about 5-10 minutes on ryzen 7 2700) due to a really large amount of proc-macro generated code in it, and since there's no persistent cache in rust-analyzer, every time I reopen the project I have to wait for quite some time for the whole thing to be processed. On the other hand, it's not like I can definitely live without types/completion from that crate..

Thanks!

Research direction

The issue names no file, test, or entry point. Start by checking whether existing rust-analyzer configuration supports excluding one dependency while retaining its types and completion; done means a documented, usable way to make that trade-off.
