Garasu (硝子)

GPU rendering engine for pleme-io applications. Provides a reusable wgpu + winit + glyphon stack so every GPU-accelerated app shares the same rendering foundation.

Components

Module	Purpose
context	wgpu device, adapter, queue, surface lifecycle
text	glyphon text layout and rasterization
shader	WGSL post-processing pipeline (ghostty/tobira pattern)
window	winit window creation with platform defaults
error	Unified error type

Usage

[dependencies]
garasu = { git = "https://github.com/pleme-io/garasu" }

use garasu::{GpuContext, TextRenderer, ShaderPipeline, AppWindow};

let gpu = pollster::block_on(GpuContext::new())?;
let text = TextRenderer::new(&gpu.device, &gpu.queue, format);

Build

cargo build
cargo test --lib

Design

• Metal on macOS, Vulkan on Linux (via wgpu backends)
• Shader plugin system: built-in + custom ~/.config/{app}/shaders/*.wgsl
• Uniforms: time, resolution, input texture + sampler
• Lock-free text rendering via glyphon
