Cannot find macro 'ui' in this scope

[Murray]

This is contents of my main.rs:
use windows::{
core::, Data::Xml::Dom::, Win32::Foundation::, Win32::System::Threading::,
Win32::UI::WindowsAndMessaging::*,
};
fn main() {

let details_window = ui! {
    Window title("Crash Details") visible(show_details) modal(true) hsize(600) vsize(400)
         halign(Alignment::Fill) valign(Alignment::Fill)
    {
         VBox margin(10) spacing(10) halign(Alignment::Fill) valign(Alignment::Fill) {
                Scroll halign(Alignment::Fill) valign(Alignment::Fill) {
                    TextBox content(details) halign(Alignment::Fill) valign(Alignment::Fill)
                },
                Button halign(Alignment::End) on_click(move || *show_details.borrow_mut() = false)
             {
                 Label text("Ok")
             }
         }
     }
};

}

It looks like you copied this code from https://hacks.mozilla.org/2024/04/porting-a-cross-platform-gui-application-to-rust/. The article is describing the ui! macro as something they wrote, not part of Rust or windows. If you want to use it, you'll have to find it and import it too.
