Taking an ndarray view on a C++ array

help
1

I'm writing a Rust library that will accept multiple large arrays from a C++ client. These arrays will be passed as simple 1D arrays, but they are really n-dimensional.

The contents of the arrays will be modified (to return updates to the client).

As the arrays are large, I don't want to copy them. So, I'm looking to create an n-dimensional view of the underlying 1D data, modifying that underlying 1D array via safe operations on an ndarray view.

My question is how I should create a view on the existing data to avoid any copies.

I believe the correct method to use would be

ndarray::ArrayViewMut.from_shape_ptr

Is that the correct approach for my use case?

It looks correct to me.

Good news. Thanks, droundy.
