std::get(std::complex)(3)

✨ NAME ✨

std::get(std::complex) — literally std::get(std::complex) 🫶

Okay bestie, you're looking at std::get(std::complex)(3) from the C++ Standard Libary manual, and it's giving tiny-accessor-with-main-character-energy ✨.

🌸 Synopsis 🌸

Defined in header <complex>:

template< std::size_t I >                                    (1)
(since C++26)
friend constexpr T& get( std::complex<T>& x );
template< std::size_t I >                                    (2)
(since C++26)
friend constexpr const T& get( const std::complex<T>& x );
template< std::size_t I >                                    (3)
(since C++26)
friend constexpr T&& get( std::complex<T>&& x );
template< std::size_t I >                                    (4)
(since C++26)
friend constexpr const T&& get( const std::complex<T>&& x );

So what's the vibe? It returns a reference to the real or imaginary part from a complex when I == 0 or I == 1, respectively. It is mainly provided for structured binding support. No cap 💅.
