std::allocator::max_size - std::allocator::max_size
size_type max_size() const throw(); (until C++11)
(since C++11)
size_type max_size() const noexcept; (deprecated in C++17)
(removed in C++20)
Returns the maximum theoretically possible value of n, for which the call
allocate(n, 0) could succeed.
In most implementations, this returns
std::numeric_limits<size_type>::max() /
sizeof(value_type).
The maximum supported allocation size
max_size returns the maximum object size supported by the
allocator
[static] (public static member function of
std::allocator_traits<Alloc>)
