std::ranges::adjacent_transform_view<V,F,N>::iterator<Const>::operator[]

constexpr decltype(auto) operator[]( difference_type n ) const
    requires ranges::random_access_range<Base>;

Returns an element at specified relative location.

Let parent_ and inner_ be the data members of the iterator. Equivalent to:

return apply([&](const auto&... iters) -> decltype(auto)
             {
                return invoke(*parent_->fun_, iters[n]...);
             },
             inner_.current_);

Parameters

Return value

The element at displacement n relative to the current location.
