Detailed Description
template<typename T>
struct pmem::detail::range_snapshotting_iterator< T >
Non-const iterator which adds elements to a transaction in a bulk.
This is done by dividing underlying array into ranges of specified (snapshot_size) size. If iterator is incremented/decremented/etc. so that it is moved to another range, this new range is added to a transaction.
For example, let's assume snapshot_size = 2, N = 6. This gives us: 0 1 | 2 3 | 4 5
If iterator is moved from 1 to 3, that means it is now in another range, and that range must be added to a transaction (elements 2 and 3).
