std::move_iterator::move_iterator - cppreference.com (original) (raw)

move_iterator(); (1) (constexpr since C++17)
explicit move_iterator( iterator_type x ); (2) (constexpr since C++17)
template< class U >move_iterator( const move_iterator<U>& other ); (3) (constexpr since C++17)

Constructs a new move_iterator.

Overload current
(1) value-initialized
(2) initialized with x(until C++20)std::move(x)(since C++20)
(3) initialized with other.current
  1. The converting constructor.
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 std::convertible_to<const U&, Iter> is modeled. (since C++20)

[edit] Parameters

x - iterator to adapt
other - iterator adaptor to copy
