# std::ranges::concat_view<Views...>::iterator<Const>::iterator

From cppreference.com
< cpp‎ | ranges‎ | concat view‎ | iterator

/*iterator*/() = default; | (1) | (since C++26)
constexpr /*iterator*/( /*iterator*/<!Const> it ) requires Const && ( std::convertible_to < ranges::iterator_t <Views>, ranges::iterator_t <const Views>> && ...); | (2) | (since C++26)
template< class... Args > constexpr explicit /*iterator*/ ( /*maybe-const*/<Const, concat_view>* parent, Args&&... args ) requires std::constructible_from </*base-iter*/, Args&&...>; | (3) | (since C++26) (exposition only*)

Constructs an iterator.

For the definition of /*maybe-const*/, see `maybe-const`﻿.

Overload | Data members
--- | ---
`parent_` | `it_`
(1) | initialized with nullptr | default-initialized
(2) | initialized with it.`parent_` | initialized with `base-iter`﻿( std::in_place_index <I>, `` ﻿std::get<I>(std::move(it.`it_`﻿))) (where I is it.`it_`﻿.index())
(3) | initialized with parent | initialized with std::forward <Args>(args)...

2) If it.`it_`﻿.valueless_by_exception() is true, the behavior is undefined.

### Parameters

it | - | a mutable iterator
parent | - | a pointer to ranges::concat_view
args | - | the arguments to initialize `it_`
