How can I create OS-specific commands?

[lean osprey]

Or in general, how should I handle the differences in api between the different runtimes?

#[tauri::command]
fn greet() {
    #[cfg(windows)]
    {
        println!("I only run on Windows");
    }
    println!("I always run");
}

#[cfg(windows)]
#[tauri::command]
fn greet() {
    println!("I run on windows");
}

#[cfg(not(windows))]
#[tauri::command]
fn greet() {
    println!("I run everywhere else");
}
