Is there interoperability between WebGPU in JS and wgpu in Rust?

[Gonkalbell]

I was thinking of trying to convert an existing tutorial from Javascript & WebGPU to Rust, so it could run both on the web and on desktop. Is it possible to convert between things like wgpu::Device to and from GPUDevice in Javascript, or access the underlying WebGPU objects from wgpu? This way, I'd be able to replace one function at a time, rather than rewrite everything at once or rely on web_sys.

From looking through this crate, it seems like any web_sys stuff is kept as a private implementation detail, but I could have just missed something. If this isn't possible yet, is there any plan in the future to enable this interop?

Not currently, but would be good thing to possibly generalize with the existing as_hal stuff for accessing underlying apis.

I have a similar question, we have a video decoding pipeline written in Rust that uses nvidia cards and cuda to decode video frames go opengl textures. I would like to use those textures from wgpu (with a OpenGL target build).

How far off is that? What are the missing pieces?

Thanks 🤗
