std::allocator_traits::max_size

From cppreference.com
Defined in header <memory>
static size_type max_size( const Alloc& a );
(since C++11)

If possible, obtains the maximum theoretically possible allocation size from the allocator a, by calling

a.max_size()

If the above is not possible (e.g. a does not have the member function max_size()), then returns std::numeric_limits<size_type>::max() (until C++17)std::numeric_limits<size_type>::max() / sizeof(value_type) (since C++17)
