A StreamRange<T> is a range of StatusOr<T> where the end-of-stream is indicated by a non-OK Status.
Callers can iterate the range using its begin() and end() members to access iterators that will work with any normal C++ constructs and algorithms that accept Input Iterators.
Callers should only consume/iterate this range.
Example: Iterating a range of 10 integers
// Some function that returns a StreamRange<int>
StreamRange<int> MakeRangeFromOneTo(int n);
StreamRange<int> sr = MakeRangeFromOneTo(10);
for (StatusOr<int> const& x : sr) {
if (!x) {
std::cerr << "Fail: " << x.status() << "\n";
} else {
std::cout << *x << "\n";
}
}
