Thousands of constants causes problems

[CraigglesO]

I have a rust file that stores all EPSG key-values: an ID whose value is a string that defines it's projection params.

The problem is that rust-analyzer basically crashes if I ever open this file or reference it.

Meanwhile, the Typescript equivalent is essentially the exact same thing, and parser/linter do not even bat an eye. I also get to use autocomplete:

I've done a lot of research on this topic and it SEEMS like the best case scenario is to either:

1. Add details in rust files I don't want rust-analyzer to activate on the file. Something like:

/// Collection of EPSG codes and their WKT definitions
#[rustfmt::skip]
#[rust_analyzer::skip]
#[allow(dead_code, unused_imports, clippy::all)]
pub mod epsg;

2. Let the editor know I don't want rust-analyzer to activate. .vscode settings.json example:

{
  "typescript.tsdk": "node_modules/typescript/lib",
  "eslint.useFlatConfig": true,
  // "files.exclude": {
  //     "rust/proj/generated": true,
  //     "rust/proj/generated/epsg.rs": true
  // },
  "rust-analyzer.files.exclude": ["rust/proj/generated/", "rust/proj/generated/epsg.rs"],
  "rust-analyzer.files.watcherExclude": ["rust/proj/generated/"],
  "rust-analyzer.exclude": ["rust/proj/generated/", "rust/proj/generated/epsg.rs"],
  "rust-analyzer.excludeGlobs": ["rust/proj/generated/**"],
  "files.watcherExclude": {
    "**/node_modules/**": true,
    "rust/proj/generated/**": true
  }
}

Neither of these work despite there being online discussions about both these things.

So the question is:

What solutions do I have? Why is it that rust-analyzer can not handle a few thousand constants?

FWIW, #[rust_analyzer::skip] is an existing thing, but it applies to bodies (constants as well) and not modules (applying it to all constants likely won't help because their body isn't the problem).

What is the crash message?

[ChayimFriedman2]

What are the logs from when you opened the file?

[CraigglesO]

Exactly, opening file.

[ChayimFriedman2]

I meant: what part of the logs is from after you opened the file?

[CraigglesO]

I just figured out how to clear logs before opening the file. 0 logs come from opening the file or after saving it.

If you want to try it

git clone [email protected]:Open-S2/gis-tools.git

And the file is rust->proj->generated->epsg.rs
