gpui-async

Overview

GPUI provides integrated async runtime for foreground UI updates and background computation.

Key Concepts:

• Foreground tasks: UI thread, can update entities (cx.spawn)
• Background tasks: Worker threads, CPU-intensive work (cx.background_spawn)
• All entity updates happen on foreground thread

Quick Start

Foreground Tasks (UI Updates)

impl MyComponent {
    fn fetch_data(&mut self, cx: &mut Context<Self>) {
        let entity = cx.entity().downgrade();
