std::move_iterator<Iter>::operator=

std::move_iterator<Iter>::operator= - cppreference.com

From cppreference.com

`template< class U > move_iterator& operator=( const move_iterator<U>& other );`		(constexpr since C++17)

Assigns other.current to current .

If `U` is not convertible to `Iter`, the program is ill-formed.	(until C++20)
This overload participates in overload resolution only if `std::is_same_v<U, Iter>` is `false` and both `std::convertible_to<const U&, Iter>` and `std::assignable_from<Iter&, const U&>` are modeled.	(since C++20)
