boost::pfr::greater_equal — std::greater_equal like comparator that returns boost::pfr::ge (x, y)

// In header: <boost/pfr/functors.hpp> template<typename T = void> struct greater_equal { // types typedef std::true_type is_transparent; // This typedef exists only if Tisvoid. // public member functions bool operator()(const T &, const T &) const; template<typename V, typename U> bool operator()(const V &, const U &) const; };

`greater_equal`

public member functions-
bool operator()(const T & x, const T & y) const;

Returns:

**true**if field of**x**greater than the field with same index of**y**and all previous fields of**x**equal to the same fields of**y**; or if each field of**x**equals the field with same index of**y**. -
template<typename V, typename U> bool operator()(const V & x, const U & y) const;

This operator allows comparison of

**x**and**y**that have different type.Requires:

Exists only if T

**is**void.
