Constructs a new iterator adaptor.
Iter
also have defined behavior.x
.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).x | - | iterator to adapt |

The following behavior-changing defect reports were applied retroactively to previously published C++ standards.
DR | Applied to | Behavior as published | Correct behavior |
---|---|---|---|
LWG 235 | C++98 | the effect of the default constructor was not specified | specified |
LWG 3435 | C++20 | the converting constructor from another reverse_iterator was not constrained | constrained |
assigns another iterator adaptor (public member function) |
|
(C++14) | creates a std::reverse_iterator of type inferred from the argument (function template) |
