ironaccelerator-webgpu

WebGPU backend for the browser. This is the WASM compute path, and only that: on native targets, Vulkan, Metal, D3D12, and OpenGL reach the same hardware directly, so routing through a portability layer would add a translation step without adding coverage.

How it works

WebGPU adapter negotiation is asynchronous and Backend is not, so this crate does not negotiate. The host awaits requestAdapter() / requestDevice(), keeps the resulting GPUDevice, and describes it once via [drv::bind_adapter]. From then on the adapter shows up in Runtime::devices() alongside every native backend.

use ironaccelerator_webgpu::drv::{bind_adapter, AdapterInfo};

// After `requestDevice()` resolves, from whatever binding layer you use:
bind_adapter(AdapterInfo {
    vendor: "nvidia".into(),
    architecture: "ampere".into(),
    shader_f16: true,
    max_buffer_size: 1 << 28,
    ..Default::default()
});

What it deliberately does not do

No buffers, pipelines, or dispatch. Those need a live GPUDevice, which stays with the host, and wrapping them would mean re-exporting a binding crate's types through this API — the coupling that made the previous wgpu-based version 98 transitive dependencies deep. The host already holds the device and can call WebGPU directly.

Consequently this crate has no dependencies beyond ironaccelerator-core and compiles for every target, wasm32-unknown-unknown included, with no feature flags and no --cfg requirements.
