Deduction guide for multimap

boost::container::multimap

Synopsis

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


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

Description

Deduction guide: allows a multimap to be constructed from the iterator range [first, last), deducing the key and mapped types from the pair value type of InputIterator and using the default comparator and allocator.
