STD::FILESYSTEM_FILESYSTEM_ERROR(3)

✨ NAME ✨

std::filesystem::filesystem_error — the exception type that the Filesystem library throws, straight out of the Library Functions Manual (section 3, bestie, we're in the library functions girlies 💅)

---

🌸 SYNOPSIS 🌸

It inherits std::system_error. That's the whole vibe. A filesystem_error is a system_error, no cap 🫶

💖 Public Member Functions

• filesystem_error (const filesystem_error &)=default — the defaulted copy constructor, iconic, does exactly what you'd think 🌈
• filesystem_error (const string &__what_arg, const path &__p1, const path &__p2, error_code __ec) — builds one with a what-string, two paths, and an error_code ✨
• filesystem_error (const string &__what_arg, const path &__p1, error_code __ec) — same energy but with just one path and the error_code 🎀
• filesystem_error (const string &__what_arg, error_code __ec) — the minimalist version: what-string + error_code, no paths attached 💜
• const error_code & code () const noexcept — hands you the error_code back, noexcept so she's safe 🍓
• filesystem_error & operator= (const filesystem_error &)=default — defaulted copy assignment, and yes she returns filesystem_error & 😌
• const path & path1 () const noexcept — the first path, noexcept, cute 🦋
• const path & path2 () const noexcept — the second path, also noexcept 🧚
• const char * what () const noexcept — the C-style string explaining the drama, noexcept 🌺

🦋 Detailed Description 🦋

Okay so real talk: std::filesystem::filesystem_error is the exception type thrown by the Filesystem library. That's the entire description and honestly she ate 🔥

🎀 Member Function Documentation 🎀

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

Returns a C-style character string that describes the general cause of the current error — and it's literally the same string you passed to the ctor, so no surprise plot twists here 😭

Reimplemented from std::runtime_error. periodt 👑
