static integer range for use in range-based for loops
This is a compile-time static variant of the IntegralRange. Apart from returning all range information statically, it casts into the corresponding std::integer_sequence.
- Note
- This range can also be used in Hybrid::forEach, resulting in a static for loop over the contained integers like a std::integer_sequence.
- Template Parameters
-
T type of integers contained in the range to first element not contained in the range from first element contained in the range, defaults to 0
