std::projected_value_t(3)

NAME
std::projected_value_t - std::projected_value_t

Synopsis
   Defined in header <iterator>
   template< std::indirectly_readable I,
             std::indirectly_regular_unary_invocable<I> Proj >
   using projected_value_t = (since C++26)
       std::remove_cvref_t<std::invoke_result<Proj&,
   std::iter_value_t<I>&>>;
   The alias template projected_value_t obtains the value type by stripping any
   reference and its topmost cv-qualifiers of the result type of applying Proj to
   std::iter_value_t<I>&.
   projected_value_t is used to determine the default value type in some algorithms
   such as ranges::contains.

Template parameters
   I - an indirectly readable type
   Proj - projection applied to an lvalue reference to value type of I
