rls not working for certain larger repos

[JosephTLyons]

I'm having an issue with what I assume to be rls. Both Atom (using the ide-rust plugin) and VS Code (using Rust (rls) plugin) are not showing syntax errors, warnings, Clippy information, etc. On smaller projects (a few files large maybe), I get all of the error / warning information, but on larger projects, I do not. Both Atom and VS Code miss the same errors on the same projects and both correctly identify the right errors on smaller projects.

Here is an example of a project that I'm not seeing any errors on: https://github.com/nushell/nushell

I'm using: macOS 10.15.3

rust v1.41

VS Code v1.41.1 Rust (rls) plugin: v0.7.0

Atom v1.43 ide-rust v0.21.2

Lastly, I initially filed this error in VS Code's rls repo before realizing the issue was the same on Atom. At least one other confirmed the issue. Here is that issue:

If this is not the correct place to file this issue, please let me know, but if anyone could help me troubleshoot this issue, it would be great. I don't recall this being an issue before and I'm not sure what broke it. I'm happy to provide any extra details if they are requested.
