Problem Description

I'm experiencing an issue where rust-analyzer reports diagnostic paths in the format ./src/xxx.rs instead of src/xxx.rs. This breaks VSCode's Ctrl+Click navigation functionality, as VSCode only recognizes the latter format for file navigation, in my environment.

Minimal Reproduction

// src/main.rs
fn error() -> Result<(), ()> {
    Err(())
}

fn main() {
    error().unwrap();
}

Expected: There's a at src/main.rs:xx in the stack backtrace
Actual: There's a at ./src/main.rs:xx in the stack backtrace, which can't be clicked to navigate in VSCode

What I've Tried

• Verified workspace root contains Cargo.toml
• Restarted rust-analyzer server multiple times
• Updated rust-analyzer and VSCode to latest versions
• Checked various rust-analyzer configuration options

Potential Solution Found

I discovered the rust-analyzer.diagnostics.remapPrefix setting. But it did not work.

{
    "rust-analyzer.diagnostics.remapPrefix": {
        "./": ""
    }
}

Questions

Are there other VSCode settings that might affect diagnostic path formatting? Any insights or alternative solutions would be greatly appreciated!
