Utility Function Object Classes
The definitions of the utility function objects are available through the <oneapi/dpl/functional> header. All function objects are implemented in the oneapi::dpl namespace.
identity: A function object type where the operator() returns the argument unchanged. It is an implementation of std::identity that can be used prior to C++20.
minimum: A function object type where the operator() applies std::less to its arguments, then returns the lesser argument unchanged.
maximum: A function object type where the operator() applies std::greater to its arguments, then returns the greater argument unchanged.
