This is a range defined by the Input Iterators returned from its begin()
and end()
members. Callers may directly iterate the RowStream
instance, which will return a sequence of StatusOr

objects.
For convenience, callers may wrap instances in a StreamOf<std::tuple<...>>
object, which will automatically parse each Row
into a std::tuple
with the specified types.
