Objective
make the following code works
Problem
Current master reports an error:
This occurs because
IntoNdProducer
is implemented for&mut ArrayBase
but not for&mut &mut ArrayBase
, and thus the following worksBut it is not intuitive.
Solution
Implement
IntoNdProducer
for&&ArrayBase
and&mut &mut ArrayBase
.&&&ArrayBase
because we usually do not use&&ArrayBase
as a function argument.AsRef<ArrayBase>
or other way.IntoNdProducer
is already defined for various types, and generic implementation break them.
