Deduction guide for map

boost::container::map

Synopsis

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


template<typename InputIterator> 
  map(ordered_unique_range_t, InputIterator, InputIterator) -> map< it_based_non_const_first_type_t< InputIterator >, it_based_second_type_t< InputIterator > >;

Description

Deduction guide: allows a map to be constructed from an already ordered, unique iterator range [first, last), deducing the key and mapped types from InputIterator and using the default comparator and allocator.
