STD::EQUAL_TO(3)

NAME</p> 💖

std::equal_to< _Tp > — bestie, it's one of the comparison functors. That's the whole job. It compares. It functors. Periodt.

---

SYNOPSIS ✨

#include <functional>

Oh and also? It inherits from std::binary_function< _Tp, _Tp, bool >. Family lineage, main character energy, we love to see it 🫶

Public Types 🎀

• typedef _Tp first_argument_type — literally the type of the first argument. no notes.
• typedef bool result_type — this is the return type. it returns a bool. it's giving yes/no, true/false, slay/not-slay.
• typedef _Tp second_argument_type — and this one? the type of the second argument. iconic symmetry tbh.

Public Member Functions 🦋

• constexpr bool operator() (const _Tp &__x, const _Tp &__y) const — the whole moment. you hand it __x and __y, it gives you back a bool. and it's constexpr, so it can do this at compile time too. not me being obsessed with a call operator 😭

Detailed Description 🌸

template<typename _Tp>
struct std::equal_to< _Tp >

"One of the comparison functors."

That's the vibe. It's a functor (a struct you can call like a function, iykyk) whose entire personality is comparing two _Tps. Lowkey the most reliable friend in <functional>. Never dramatic, never guessing, just comparing. 💅

Member Typedef Documentation 🧚

typedef _Tp std::binary_function< _Tp, _Tp, bool >::first_argument_type

[inherited] — so this one isn't even originally hers, she got it from the family.

first_argument_type is the type of the first argument.

typedef bool std::binary_function< _Tp, _Tp, bool >::result_type

[inherited] — same deal, inherited.

result_type is the return type.

typedef _Tp std::binary_function< _Tp, _Tp, bool >::second_argument_type

[inherited] — yep, inherited again. generational wealth fr fr.

second_argument_type is the type of the second argument.

okay that's the whole page bestie!! this one lives in the libstdc++ manual, filed under std::equal_to< _Tp >(3) — go forth and compare things, you've got this 🌈⭐🫶
