std::basic_...m::operator=(3)

💖 NAME 💖

std::basic_ispanstream::operator= — std::basic_ispanstream::operator= (yes bestie, the name is literally the name, and we respect the minimalism 💅)

okay so this is std::basic_...m::operator=(3) from the C++ Standard Libary manual, and we're about to get into the move-assignment of it all ✨

---

🦋 SYNOPSIS 🦋

basic_ispanstream& operator=( basic_ispanstream&& other );

(1) (since C++23)

basic_ispanstream& operator=( const basic_ispanstream& ) = delete;

(2) (since C++23)

🌸 the actual tea 🌸

1. Move assignment (1) — Move assigns other to *this, effectively move-assigning both the std::basic_istream base class subobject and the wrapped std::basic_spanbuf. it's giving "both of you are moving, no cap" 🫶
2. Copy assignment (2) — Copy assignment operator is deleted. basic_ispanstream is not copy assignable. periodt, she does not do copies 🙈

Note that move assignment operator of the base class swaps all stream state variables (except for rdbuf()) between *this and other. the way that rdbuf() is the exception is so specific, iykyk 💀

It is implementation-defined whether the std::basic_spanbuf wrapped in other still holds an underlying buffer after the move assignment. so like, that part is left up to the implementation bestie, don't come for me 🌈

🍓 PARAMETERS 🍓

• other — another stream to move from

⭐ RETURN VALUE ⭐

*this — cute, iconic, returns itself 💖

💀 EXCEPTIONS 💀

May throw implementation-defined exceptions. so yeah, implementation-defined again, the mystery of it all 😭

🙈 EXAMPLE 🙈

This section is incomplete.

Reason: no example 🫠

👑 SEE ALSO 👑

• operator= assigns a basic_spanbuf object (C++23) (public member function of std::basic_spanbuf<CharT,Traits>)
• operator= move-assigns from another basic_istream (C++11) (protected member function)
