How can I remove type annotation help when using rust-analyzer?

For VS Code, I use rust-analyzer to handle syntax highlighting and flychecking.

How do I remove the inlay type and parameter annotations in grey below?

If you're not using VS Code you'll need to manually edit the JSON config file of your rust-analyzer install (helpful link to the documentation). Basically

1. Open the JSON config file in your favourite text editor
2. Add a new property to the root of the JSON object like so:

{
    "inlayHints": {
        "typeHints": false,
        "parameterHints": false
    },
    // further configuration
}

Old answer for VS Code:

In Visual Studio Code you can easily do this.

1. Open the settings page (Ctrl+,)
2. Search for "rust-analyzer inlay"
3. Uncheck things you don't want
   • In your case that would be "Parameter Hints" and "Type Hints"
