Detailed Description

template<bool const_range>
template<typename outer_it_type>
class seqan3::detail::chunk_view< urng_t >::basic_input_iterator< const_range >::input_helper_iterator< outer_it_type >

Helper iterator class to be used as iterator type in the subrange of this iterators value_type.

Template Parameters

urng_t

The type of the underlying range. Must model std::ranges::view and std::input_range but not std::forward_range.

The only purpose of this class is to wrap the iterator type it is inheriting from (urng_it_t) with the addition of decrementing the member variable basic_input_iterator::remaining when being incremented. This way, the basic_input_iterator can keep track of how many times the basic_input_iterator::urng_begin has been incremented within a chunk. A chunk can therefore be represented by a std::ranges::subrange<input_helper_iterator, sentinel_t>.
