Crate aetna_winit_wgpu 

Optional desktop host for running Apps against a real wgpu surface in a winit window.

Most native apps should use this crate instead of calling aetna-wgpu directly:

use aetna_core::prelude::*;

fn main() -> Result<(), Box<dyn std::error::Error>> {
    let viewport = Rect::new(0.0, 0.0, 720.0, 480.0);
    aetna_winit_wgpu::run("My Aetna App", viewport, MyApp::default())
}

The host owns the event loop, window, device/queue, surface configuration, render pass boundaries, input mapping, IME forwarding, and animation redraw cadence. Your code owns the App: application state, App::build, App::on_event, optional hotkeys, custom shaders, and theme.

run takes an App and runs an event loop that:

• Calls App::build on every redraw, applying current hover/press visuals automatically before paint.
• Routes winit pointer events through the renderer’s hit-tester and dispatches events back via App::on_event.
• Routes Tab/Shift-Tab through focus traversal and Enter/Space/Escape through keyboard events.
• Copies the current Aetna text selection to the native clipboard on Ctrl/Cmd+C.
• Requests a redraw whenever interaction state changes (mouse move, button down/up) so hover/press visuals are immediate.

Use run_with_config when a simple app needs a fixed redraw cadence for external live state such as meters. Put per-frame state refresh in App::before_build. For fully custom render-loop integration, bypass this crate and call aetna_wgpu::Runner directly.
