std::bad_any_cast(3)

💖 NAME

okay so bestie, this is the page for std::bad_any_cast(3) from the C++ Standard Libary, and the NAME section is literally std::bad_any_cast - std::bad_any_cast. yes, she contains multitudes 💅.

✨ Synopsis

Defined in header <any>:

class bad_any_cast : public std::bad_cast;  (since C++17)

Defines a type of object to be thrown by the value-returning forms of std::any_cast on failure. so if a value-returning any_cast fails, this is the exception type it throws. no cap. 😭

🧸 Member functions

• constructor — constructs a new bad_any_cast object (public member function)
• operator= — replaces the bad_any_cast object (public member function)
• what — returns the explanatory string (public member function)

💅 std::bad_any_cast::bad_any_cast

bad_any_cast() noexcept;                            (1) (since C++17)
bad_any_cast( const bad_any_cast& other ) noexcept; (2) (since C++17)

Constructs a new bad_any_cast object with an implementation-defined null-terminated byte string which is accessible through what().

1. Default constructor.
2. Copy constructor. If *this and other both have dynamic type std::bad_any_cast then std::strcmp(what(), other.what()) == 0.

🫶 Parameters

• other — another exception object to copy

🌸 std::bad_any_cast::operator=

bad_any_cast& operator=( const bad_any_cast& other ) noexcept; (since C++17)

Assigns the contents with those of other. If *this and other both have dynamic type std::bad_any_cast then std::strcmp(what(), other.what()) == 0 after assignment.

🫶 Parameters

• other — another exception object to assign with

🎀 Return value

*this

🦋 std::bad_any_cast::what

virtual const char* what() const noexcept;  (since C++17)

Returns the explanatory string.

🫶 Parameters

(none)

🎀 Return value

Pointer to a null-terminated string with explanatory information. The string is suitable for conversion and display as a std::wstring.

The pointer is guaranteed to be valid at least until the exception object from which it is obtained is destroyed, or until a non-const member function (e.g. copy assignment operator) on the exception object is called. 🫠

🗒️ Notes

Implementations are allowed but not required to override what().

🧸 Member functions

• destructor — destroys the exception object [virtual] (virtual public member function of std::exception)
