Q: Where to find docs for emscripten_webgpu_import_device et.al ?

Hi!

I'm wondering where I can read up on emscripten_webgpu_import_device and the related functions?
My searches keep turning up empty 🤔

Regards,

There isn't really any documentation, the best I can point you at is the test:

emscripten/test/webgpu_jsvalstore.cpp

Line 49 in cf7f6b3

wgpu::Device device = wgpu::Device::Acquire(emscripten_webgpu_import_device(deviceHandle.Get()));

HOWEVER, please note that Emscripten's built-in bindings are being deprecated (#24265) in favor of the external fork "emdawnwebgpu" which no longer has emscripten_webgpu_import_device exposed in C, instead it only has WebGPU.importJsDevice in JS. You would call this from JS to import it into the bindings, then pass the handle from JS to C and cast it to WGPUDevice.

Sorry I don't have any examples of this to point at either. I have filed https://crbug.com/416377157 about it.

Thanks Kai for the info!
