// In header: <boost/container/set.hpp>
template<typename InputIterator,typename AllocatorOrCompare>set(ordered_unique_range_t,InputIterator,InputIterator,AllocatorOrCompareconst&);
Description
Deduction guide: allows a set to be constructed from an already ordered, unique iterator range [first, last), deducing the key type from InputIterator. The trailing argument is used as the allocator if it is an allocator type, otherwise it is used as the comparator.
