Method new_from_device_ptr

src/core/array.rs:356–370

Constructs a new Array object from device pointer The example show cases the usage using CUDA API, but usage of this function will be similar in CPU and OpenCL backends also. In the case of OpenCL backend, the pointer would be cl_mem. A short example of how to create an Array from device pointer is shown below but for detailed set of examples, please check out the tutorial book pages: - [Interope
