gapp-winit
An abstract event loop library for winit-based applications with support for OpenGL/glutin and wgpu backends. Integrates seamlessly with gapp traits for clean separation of input, update, render, and present.
Supports native (Windows/Linux/macOS) and WASM. Fixed-timestep FPS cap, automatic resize handling.
Features
- Backend-agnostic: Switch between OpenGL and wgpu via Cargo features.
- Trait-based: Implement
WindowInput,Present,Render(gapp),Update(gapp). - Cross-platform: Full WASM support (HTML canvas).
- Performance: Fixed timestep, on-demand redraw, FPS sleep (native).
| Feature | OpenGL | wgpu |
|---|---|---|
| Native | ✅ | ✅ |
| WASM | ✅ | ✅ |
| Default | ✅ | ❎️ |
Quickstart
For reference, have a look at the template program. It also can be used as a base for your program.
Traits Overview
WindowInput<C, R>: Handle allWindowEvents (post-resize/redraw). Callevent_loop.exit()on close.Present<R>: Submit frame (e.g.,queue.submit(),surface.swap_buffers()).Render<R>/Update(from gapp): Standard render/update loop.
Resize is auto-handled.
FPS can be supplied to run.
