std::refere...r::operator=(3)

💖 std::refere...r::operator=(3) 💖

Ok bestie, we're in the C++ Standard Libary manual today and the main character is std::reference_wrapper::operator=. Yes, that's the title. We're doing this. 🫶

🌸 NAME 🌸

std::reference_wrapper::operator= — std::reference_wrapper::operator= ✨

(Yes, same thing twice. It's giving "the function so iconic they named it twice." 💅)

🦋 Synopsis 🦋

Here's the signature exactly as the page lays it out — copy assignment energy, since C++11, and constexpr since C++20:

reference_wrapper& operator=( const reference_wrapper&       (since
C++11)
other ) noexcept;
(constexpr since C++20)

Okay so this is the Copy assignment operator. It drops the current reference and stores a reference to other.get(). That's the whole vibe. 🔥

🎀 Parameters 🎀

• other — reference wrapper to copy. That's it. That's the parameter. 🍓

👑 Return value 👑

• *this — yup, it returns itself. Main character returns main character. 💅

Source/version and date, as promised: this page comes from http://cppreference.com, version 2024.06.10, and the footer date is 2024.06.10. Byeee, go copy-assign something cute 💖✨
