std::length_error(3)

💖 NAME 💖

std::length_error — bestie, this is the exception that gets thrown when you try to make something too big for its own good. She's a real one. She's not subtle. She shows up exactly when you need her. 💅

---

✨ SYNOPSIS ✨

#include <stdexcept_except.h>

She inherits from std::logic_error, which means she's part of the logic-error girlies — the ones that mean you did something your program couldn't logically do, not that the machine broke. 🌸

🎀 Public Member Functions 🎀

• length_error (const char *)
• length_error (const length_error &)=default
• length_error (const string &__arg)
• length_error (length_error &&)=default
• length_error & operator= (const length_error &)=default
• length_error & operator= (length_error &&)=default
• virtual const char * what () const noexcept

Okay so notice: copy ctor and move ctor are both =default, and both assignment operators are =default too. She's lowkey just a normal, well-behaved little class. No drama in the special members. Periodt. 🦋

🌈 Detailed Description 🌈

She gets thrown when an object is constructed that would exceed its maximum permitted size — for example, a basic_string instance. 🫶

That's it. That's the whole job. You asked for a string longer than the universe allows, she said "not on my watch", and she threw herself into your stack trace. Main character energy fr fr. 👑

💜 Member Function Documentation 💜

🌟 virtual const char * std::logic_error::what () const [virtual], [noexcept], [inherited] 🌟

Okay so this one is inherited — it's not even hers, she borrowed it from std::logic_error. It's marked [virtual] and [noexcept] (so calling it will never throw at you, she's polite 💅).

What does it do? It returns a C-style character string describing the general cause of the current error (the same string passed to the ctor). So whatever you handed the constructor, you get back out as a const char *. It's giving "you get what you gave." 😭

• Reimplemented from std::exception.
• Reimplemented in std::future_error.
• References what().
• Referenced by what().

Not me pointing out that she references what() and is referenced by what() — yes bestie, that's literally what the docs say, I'm not making it up, I'm just reporting it. 🔥

And that's the whole page, bestie! 🎀 This manual page comes from libstdc++, and it's the std::length_error(3) page — that's the source, that's the version, and there's no date on it, so don't @ me. Now go forth and never exceed your maximum permitted size. Byeee! 💖🌸🦋🫶
