# Goldy: Modern GPU Library
[](https://opensource.org/licenses/MIT)
A modern Rust GPU library that deliberately sheds legacy baggage. Goldy targets only modern GPU APIs (Vulkan 1.3+, DX12, Metal) and can therefore be significantly simpler than libraries that must maintain backward compatibility.
## Quick Example
```rust
use goldy::{Instance, DeviceType, Buffer, BufferUsage, Color, CommandEncoder, FrameOutput, TextureFormat};
fn main() -> anyhow::Result<()> {
let instance = Instance::new()?;
let device = instance.create_device(DeviceType::DiscreteGpu)?;
let frame = FrameOutput::new(&device, 800, 600, TextureFormat::Rgba8Unorm);
let mut encoder = CommandEncoder::new();
{
let mut pass = encoder.begin_render_pass();
pass.clear(Color::CORNFLOWER_BLUE);
}
let pixels = frame.render(encoder)?;
Ok(())
}
```
## Features
| **Rust-native** | Idiomatic Rust API, not a wrapper around C |
| **Modern-only** | Vulkan 1.3+, DX12, Metal baseline |
| **Slang shaders** | Single shader language for all backends |
| **Legacy-free** | No OpenGL, no Vulkan <1.3, no OpenCL |
| **Unified** | Graphics and compute in one API |
| **Fast-moving** | Not a standard—can iterate quickly |
| **WASI-ready** | Designed for sandboxed GPU access |
## Installation
```toml
[dependencies]
goldy = "0.1"

## Motivation
Goldy is inspired by Sebastian Aaltonen's ["No Graphics API"](https://www.sebastianaaltonen.com/blog/no-graphics-api) vision of what's possible with modern GPU hardware. By targeting only modern GPUs (2018+), Goldy can:
- Use dynamic rendering (no render pass objects)
- Use bindless descriptors (no descriptor sets)
- Assume coherent caches (simpler synchronization)
- Provide a dramatically simpler API
Goldy is also inspired by:
- Wayland's compositor architecture
- Ralph Levien's ["Requiem for piet-gpu-hal"](https://raphlinus.github.io/rust/gpu/2023/01/07/requiem-piet-gpu-hal.html)
- Slang's vision for unified shader language
- [WGPU](https://gfx-rs.github.io/2019/03/06/wgpu.html)
- This paper on GPU abstractions: https://www.kom.tu-darmstadt.de/papers/KCGS17.pdf
