Constructs a new iterator adaptor.

1) Default constructor. The underlying iterator is value-initialized. Operations on the resulting iterator have defined behavior if and only if the corresponding operations on a value-initialized Iter also have defined behavior.

2) The underlying iterator is initialized with x (until C++20)std::move(x) (since C++20).

3) The underlying iterator is initialized with that of other. The behavior is undefined if U is not convertible to Iter (until C++20)This overload participates in overload resolution only if U is not the same type as Iter and std::convertible_to<const U&, Iter> is modeled (since C++20).

Parameters

x	-	iterator to adapt
other	-	iterator adaptor to copy

Defect reports

The following behavior-changing defect reports were applied retroactively to previously published C++ standards.

DR	Applied to	Behavior as published	Correct behavior
LWG 3435	C++20	the converting constructor from another move_iterator was not constrained	constrained
