27.5.3.3.1 move_­iterator constructors [move.iter.op.const]

🔗
constexpr move_iterator();
1
#
Effects: Constructs a move_­iterator, value-initializing current.
Iterator operations applied to the resulting iterator have defined behavior if and only if the corresponding operations are defined on a value-initialized iterator of type Iterator.
🔗
constexpr explicit move_iterator(Iterator i);
2
#
Effects: Constructs a move_­iterator, initializing current with i.
🔗
template <class U> constexpr move_iterator(const move_iterator<U>& u);
3
#
Effects: Constructs a move_­iterator, initializing current with u.base().
4
#
Requires: U shall be convertible to Iterator.
