std::common_type<std::basic_const_iterator>

Defined in header <iterator> 
template< class T, std::common_with<T> U >
    requires std::input_iterator<std::common_type_t<T, U>>
struct common_type<std::basic_const_iterator<T>, U>;
 (1) (since C++23) 
template< class T, std::common_with<T> U >
    requires std::input_iterator<std::common_type_t<T, U>>
struct common_type<U, std::basic_const_iterator<T>>;
 (2) (since C++23) 
template< class T, std::common_with<T> U >
    requires std::input_iterator<std::common_type_t<T, U>>
struct common_type<std::basic_const_iterator<T>,
                   std::basic_const_iterator<U>>;
 (3) (since C++23)

The common type of two basic_const_iterators or a basic_const_iterator and another iterator type is a basic_const_iterator of the common underlying type.

The common type is defined only if T and U share a common type which models input_iterator.
