Winit Aync Executor

WAE is an async executor that use Winit event loop to drive the future that is ready to run.

Example

use std::error::Error;
use std::rc::Rc;
use wae::{Signal, WindowHandler, WinitWindow};
use winit::dpi::{PhysicalPosition, PhysicalSize};
use winit::event::{DeviceId, ElementState, InnerSizeWriter, MouseButton};
use winit::window::{Window, WindowId};

fn main() {
    wae::run(run()).unwrap()
}

async fn run() {
    let attrs = Window::default_attributes();
    let win = Rc::new(MyWindow {
        win: wae::create_window(attrs).unwrap(),
        close_requested: Signal::default(),
    });

    wae::register_window(&win);

    win.close_requested.wait().await;
}

struct MyWindow {
    win: Window,
    close_requested: Signal<()>,
}

impl WinitWindow for MyWindow {
    fn id(&self) -> WindowId {
        self.win.id()
    }
}

impl WindowHandler for MyWindow {
    fn on_resized(&self, _: PhysicalSize<u32>) -> Result<(), Box<dyn Error + Send + Sync>> {
        Ok(())
    }

    fn on_close_requested(&self) -> Result<(), Box<dyn Error + Send + Sync>> {
        let _ = self.close_requested.set(());
        Ok(())
    }

    fn on_focused(&self, _: bool) -> Result<(), Box<dyn Error + Send + Sync>> {
        Ok(())
    }

    fn on_cursor_moved(
        &self,
        _: DeviceId,
        _: PhysicalPosition<f64>,
    ) -> Result<(), Box<dyn Error + Send + Sync>> {
        Ok(())
    }

    fn on_cursor_left(&self, _: DeviceId) -> Result<(), Box<dyn Error + Send + Sync>> {
        Ok(())
    }

    fn on_mouse_input(
        &self,
        _: DeviceId,
        _: ElementState,
        _: MouseButton,
    ) -> Result<(), Box<dyn Error + Send + Sync>> {
        Ok(())
    }

    fn on_scale_factor_changed(
        &self,
        _: f64,
        _: InnerSizeWriter,
    ) -> Result<(), Box<dyn Error + Send + Sync>> {
        Ok(())
    }

    fn on_redraw_requested(&self) -> Result<(), Box<dyn Error + Send + Sync>> {
        Ok(())
    }
}
