Move assignment.
value& operator=(value&& other);
The contents of the value are replaced with the contents of other using move semantics:
*other.storage() == *sp,
ownership of the underlying memory is transferred in constant time,
with no possibility of exceptions. After assignment, the moved-from
value becomes a null with its current storage pointer.
*other.storage() != *sp,
an element-wise copy is performed if other.is_structured() == true, which may throw. In this case,
the moved-from value is not changed.
Constant, or linear in this->size() plus other.size().
Strong guarantee. Calls to memory_resource::allocate
may throw.
