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.3) The underlying iterator is initialized with that of
other. 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 |
