std::functi...::operator()(3)

💖 NAME 💖

okay bestie, welcome to the std::function_ref::operator() page from the C++ Standard Libary manual — the header is doing that truncated std::functi...::operator()(3) thing, iykyk ✨

The NAME line is literally std::function_ref::operator() - std::function_ref::operator(). self-titled icon behavior, no cap 💅

---

🦋 SYNOPSIS 🦋

Here's the signature, copied exactly because we do not mess with code:

R operator()( Args... args ) const noexcept(/*noex*/);  (since C++26)

Okay so operator() invokes the stored thunk-ptr with bound-entity as its first parameter and the rest of the parameters args.

The /*noex*/ part of operator() is identical to those of the template parameter of std::function_ref.

Equivalent to return thunk-ptr(bound-entity, std::forward<Args>(args)...);. periodt 💅

---

🌸 PARAMETERS 🌸

• args — rest parameters to pass to the stored thunk-ptr

---

💖 RETURN VALUE 💖

thunk-ptr(bound-entity, std::forward<Args>(args)...). that's the whole vibe 🫶

---

🔥 EXCEPTIONS 🔥

Propagates the exception thrown by the underlying function call. if the underlying call throws, this doesn't swallow it — it lets it through 😭

---

🎀 EXAMPLE 🎀

👑 SEE ALSO 👑

• operator() invokes the target — public member function of std::function<R(Args...)>
• operator() calls the stored function — public member function of std::reference_wrapper<T>
