std::experi...eater_equal(3)

💅 std::experimental::ranges::greater_equal 💅

okay so welcome to the std::experimental::ranges::greater_equal(3) page, bestie — this one comes straight outta the C++ Standard Libary manual (yes, the manual name is literally spelled like that, periodt).

---

🌸 NAME 🌸

std::experimental::ranges::greater_equal — std::experimental::ranges::greater_equal

that's the whole NAME section, she's short and iconic 💖

---

✨ SYNOPSIS ✨

Defined in header <experimental/ranges/functional>

template< class T = void >

    requires StrictTotallyOrdered<T> ||
             Same<T, void> ||
(ranges TS)
             /* < on two const T lvalues invokes a built-in operator
        comparing pointers */

struct greater_equal;
template<>
(ranges TS)
struct greater_equal<void>;

Function object for performing comparisons. The primary template invokes operator< on const lvalues of type T and negates the result. The specialization greater_equal<void> deduces the parameter types of the function call operator from the arguments (but not the return type).

All specializations of greater_equal are Semiregular.

---

🧩 MEMBER TYPES 🧩

• Member type: is_transparent (member only of greater_equal<void> specialization) — Definition: /* unspecified */

---

🛠️ MEMBER FUNCTIONS 🛠️

• operator() — checks if the first argument is greater than or equal to the second (public member function)

🎯 std::experimental::ranges::greater_equal::operator() 🎯

here are the two overloads, bestie:

constexpr bool operator()(const T& x, const T& y) const;

(1) — member only of primary greater_equal<T> template

template< class T, class U >

    requires StrictTotallyOrderedWith<T, U> ||
             /* std::declval<T>() <
                std::declval<U>() resolves to
                a built-in operator comparing
                pointers */

constexpr bool operator()(T&& t, U&& u) const;

(2) — member only of greater_equal<void> specialization

1. Compares x and y. Equivalent to return !ranges::less<>{}(x, y);.
2. Compares t and u. Equivalent to return !ranges::less<>{}(std::forward<T>(t), std::forward<U>(u));.

📝 NOTES 📝

Unlike std::greater_equal, ranges::greater_equal requires all six comparison operators <, <=, >, >=, == and != to be valid (via the StrictTotallyOrdered and StrictTotallyOrderedWith constraints) and is entirely defined in terms of ranges::less. However, the implementation is free to use operator>= directly, because those concepts require the results of the comparison operators to be consistent.
