Description

Hey! I'm looking for some guidance on how to display files in file tree plugins in a different state based on this plugin.
Basically - display file red if it contains errors, yellow if it has clippy warnings, you know the usual IDE stuff.
I'd say it's the only thing I miss from the vscode

I get that it might be more in the rust-analyzer area, but rust-analyzer doesn't have any lua setup per se, and I'm not a great lua user

I might even be down writing another lua plugin for this, but I have no idea where to start

Example Code

not really applicable

Neovim version (nvim -v)

v0.11.0

Operating system/version

ubuntu 24.04

Output of :checkhealth rustaceanvim

Hey 👋

What you're requesting isn't really specific to rustaceanvim. You can use :h vim.diagnostic.get to get diagnostics, regardless of the language.
rust-analyzer publishes diagnostics for the whole workspace (not all language servers do).

Regarding how to implement that in the file browser plugins, I'd suggest asking for guidance there.
