Module real 

Real wgpu compute backend, enabled only with the wgpu-backend feature.

Provides GPU buffer management, WGSL shader dispatch, and CPU-side readback using wgpu 29’s cross-platform Vulkan / Metal / DX12 backends.

Thread safety

wgpu::Device and wgpu::Queue are Send + Sync. The shader cache is protected by a Mutex, making WgpuBackendReal safe to share across threads (though individual dispatches are synchronous on the calling thread).

Usage

// With the wgpu-backend feature enabled:
use oxiphysics_gpu::compute::wgpu_backend::real::WgpuBackendReal;

let mut backend = WgpuBackendReal::try_new()?;
let h = backend.create_buffer_f64(128);
backend.write_buffer_f64(h, &vec![1.0_f64; 128]);
backend.dispatch_wgsl(
    WGSL_SPH_DENSITY, "sph_density",
    &[(h, wgpu::BufferBindingType::Storage { read_only: false })],
    [2, 1, 1],
)?;
let out = backend.read_buffer_f64(h);
