Crate dear_app 

Winit + WGPU application runtime for dear-imgui-rs.

The runtime keeps the main window, Dear ImGui context, and user Application stable while replacing only GPU-owned state after a device-loss signal.

use dear_app::AppConfig;

dear_app::run_ui(AppConfig::default(), |ui| {
    ui.window("Hello").build(|| ui.text("Hello, world!"));
})?;

Re-exports

pub use dear_imgui_rs as imgui;

pub use wgpu;
