Window and event management for Astrelis engine.

This crate provides the App trait for game loop implementation, window creation/management, and event batching for efficient processing.

Quick Start

use astrelis_winit::{app::{run_app, App, AppCtx}, FrameTime, WindowId, event::EventBatch};

struct MyApp;

impl App for MyApp {
    fn update(&mut self, _ctx: &mut AppCtx, _time: &FrameTime) {
        // Game logic update
    }

    fn render(&mut self, _ctx: &mut AppCtx, window_id: WindowId, events: &mut EventBatch) {
        // Rendering logic per window
    }
}

fn main() {
    run_app(|_ctx| Box::new(MyApp));
}

App Lifecycle

Methods are called in this order each frame:

1. App::on_start() - Once at startup
2. App::begin_frame() - Start of each frame
3. App::update() - Game logic update
4. App::fixed_update() - Physics/fixed timestep (repeated as needed)
5. App::render() - Per-window rendering (called for each window)
6. App::end_frame() - End of each frame
7. App::on_exit() - Once at shutdown

Event Batching

Events are collected and batched per-window using EventBatch. Access events in the render() method to handle input for each window separately.

Features

• Window creation and management via window::WindowBackend
• Event loop integration with winit
• Frame timing and fixed timestep support via FrameTime
• Window resizing, focus, and lifecycle events
