Struct CrossThreadTask 

pub struct CrossThreadTask { /* private fields */ }

A task sent from a background thread to the window thread.

Must be Send because it crosses thread boundaries. Carries a priority so the scheduler can route it to the correct queue.

Example

// On background thread:
let data = reqwest::get(url).await?;

// Send result back to window thread at Normal priority:
sender.send(CrossThreadTask::new(TaskPriority::Normal, move || {
    btn.set_text(&data.title);  // safe! runs on window thread
}));
