1//! `egui` integration for `egui-async`.
2//!
3//! This module provides the [`EguiAsyncPlugin`], which is necessary to integrate
4//! `egui-async` into an `egui` application, alongside async immediate mode widgets.

13/// The plugin that drives `egui-async`'s per-frame updates.
14///
15/// This plugin **must be registered** with `egui` for `egui-async` to work.
16/// It is responsible for updating frame timers and setting the global `egui::Context`
17/// so that background tasks can request repaints.
18///
19/// The easiest way to register it is to call `ctx.plugin_or_default::<EguiAsyncPlugin>();`
20/// in your `eframe::App::update` method or equivalent. `egui` ensures this is a
21/// cheap, idempotent operation.
