• exception (const exception &)=default — defaulted, literally. Same energy, no custom code. ✨
• exception (exception &&)=default — also defaulted. Move over, bestie. 💨
• exception & operator= (const exception &)=default — defaulted copy assignment. Slay. 💅
• exception & operator= (exception &&)=default — defaulted move assignment. Obsessed. 💖
• virtual const char * what () const noexcept — the what() member; full tea is below. 👇

🌸 Detailed Description 🌸

Base class for all library exceptions. That's the whole mood. 👑

This is the base class for all exceptions thrown by the standard library, and by certain language expressions. You are free to derive your own exception classes, or use a different hierarchy, or to throw non-class data (e.g., fundamental types). No gatekeeping, bestie — do your own thing. 🦋

🦋 what() — the signature, exactly 🦋

virtual const char * std::exception::what () const [virtual],  [noexcept]

Returns a C-style character string describing the general cause of the current error. She gives you the general cause, not the whole novel. 💬
