- bounds_t
  Class represents a half-open interval with lower and upper bounds. #include <sdlt/bounds.h>
- sdlt::bounds Template Function
  Factory function provided for creation of bounds_t objects. #include <sdlt/bounds.h>
- n_bounds_t
  Variadic template class to describe the valid iteration space over an N-dimensional container. #include <sdlt/n_bounds.h>
- n_bounds_generator
  Facilitates simple creation of n_bounds_t objects. #include <sdlt/n_bounds.h>
- bounds_d Template Function
  Provides a consistent way to determine the bounds of a dimension for a multi-dimensional object. #include <sdlt/n_extent.h>
