Summary

WasmGPU.python.copyInto copies a validated Python buffer into an existing C-contiguous CPUndarray or GPUndarray. Source and destination dtype, shape, and byte length must match. A GPU destination must have GPUBufferUsage.COPY_DST.

Syntax

WasmGPU.python.copyInto(dst: CPUndarray | GPUndarray, src: PythonArraySource): void
wgpu.python.copyInto(dst, src);

Parameters

Name	Type	Required	Description
dst	CPUndarray \| GPUndarray	Yes	Existing C-contiguous destination ndarray.
src	PythonArraySource	Yes	Matching C-contiguous Python buffer or proxy.
