Error E0107 - False positive while using tauri

Problem description

When you use Tauri and create a command to receive an event from the "frontend" and want to access the window as a param, it throws an E0107 Error for the Window data type that is a false positive. Reference is the official Tauri documentation

Steps to reproduce

Set up a tauri app and add an event to receive the invoked event from the "frontend".

#[tauri::command(async)]
async fn app_ready(window: Window) {
    println!("Received Event");
}

Just found this too now. Glad its reported.

Though looking at the source I can see why its flagged

pub struct Window<R: Runtime> {

[sekwah41]

I think technically the right way to state it is

#[tauri::command]
fn set_ui_theme<R: Runtime>(is_dark_mode: bool, window: tauri::Window<R>) {
    println!("set_ui_theme! {}", is_dark_mode);
}

So this plugin actually is probably correct to warn about it, but its doing red warnings against legit rust code.

The plugin shows error annotation in this case because it doesn't expand attribute procedural macros by default for now.
As a result, it shows false positive error here.
But you can enable expansion of attributes macros with org.rust.macros.proc.attr experimental feature and it should solve your issue.
Don't forget to reload the project model via Refresh Cargo Projects action in Cargo tool window after it.
See #6908 for more details
