std::allocator_traits<Alloc>::max_size

static size_type max_size( const Alloc& a ) noexcept;

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).

Parameters

(none).

Return value

Theoretical maximum allocation size.
