std::nested_exception::operator= – std::nested_exception::operator= Synopsis nested_exception &operator=(const nested_exception &other) noexcept = default; (since C++ 11) Replaces the stored exception with the one held in other. Parameters other – nested exception to replace the contents with Return value *this
std::nested_exception::nested_ptr – std::nested_exception::nested_ptr Synopsis std::exception_ptr nested_ptr() const noexcept; (since C++11) Returns a pointer to the stored exception, if any. Parameters (none) Return value (none)
