1//! OxiCUDA WebGPU backend — cross-platform GPU compute via `wgpu` and WGSL.
2//!
3//! Provides a [`WebGpuBackend`] that implements the [`oxicuda_backend::ComputeBackend`] trait
4//! from `oxicuda-backend`, using `wgpu` to target Vulkan, Metal, Direct3D 12,
5//! and the browser WebGPU API from a single Rust crate.
6//!
7//! # Quick Start
8//!
9//! ```rust,no_run
10//! use oxicuda_webgpu::WebGpuBackend;
11//! use oxicuda_backend::ComputeBackend;
12//!
13//! let mut backend = WebGpuBackend::new();
14//! backend.init().expect("WebGPU init failed");
15//!
16//! // Allocate 1 KiB on the GPU.
17//! let ptr = backend.alloc(1024).expect("alloc failed");
18//! backend.free(ptr).expect("free failed");
19//! ```
20//!

38//! # WGSL Shader Generation
39//!
40//! The [`shader`] module provides helpers that produce WGSL source strings for
41//! common kernels (GEMM, element-wise ops, reductions).
