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 |
