Deduction guide for flat_set

boost::container::flat_set

Synopsis

// In header: <boost/container/flat_set.hpp>


template<typename InputIterator, typename AllocatorOrCompare> 
  flat_set(ordered_unique_range_t, InputIterator, InputIterator, 
           AllocatorOrCompare const &) -> flat_set< it_based_value_type_t< InputIterator >, typename dtl::if_c< dtl::is_allocator< AllocatorOrCompare >::value, std::less< it_based_value_type_t< InputIterator > >, AllocatorOrCompare >::type, typename dtl::if_c< dtl::is_allocator< AllocatorOrCompare >::value, AllocatorOrCompare, new_allocator< it_based_value_type_t< InputIterator > > >::type >;

Description

Deduction guide: allows a flat_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.
