Is there a iterative version of select?

[astrojhgu]

I'd like to iterate an Array along one axis over a set of selected indices. However I am not able to find such a method.

I notice that the fn select(&self, axis, &[Idx]) returns a copy, which is inefficient for read only iterative operation.

Is there such a method fulfill this purpose?

e.g., if there is hypothetical method, I'd like to use it in the way

for s in someArray.selected_indices(Axis(0), &[1,2,4,8,16]){
    //some read only operation to s
}

It's just a matter of calling the right slice or index axis method in each iteration

Let me complement my question.

I actually need to call an into_par_iter on the hypothetical selected_indices so that I can zip it with other parallel iterators.

I'd say look at what you can do from existing apis
