egui_widget_ext 0.3.0

//! # Toast Demo Example
//!
//! This example demonstrates the usage of the `toast` widget from the `egui_widget_ext` crate.
//! It shows how to display toast notifications with different durations, colors, and messages.
//! Toasts are transient and disappear after a set duration.
//!
//! To run this example:
//! ```sh
//! cargo run --example toasts
//! ```
