24.3.10.2 Constructors, copy, and assignment [forward.list.cons]

explicit forward_list(const Allocator&);
Effects: Constructs an empty forward_list object using the specified allocator.
Complexity: Constant.
explicit forward_list(size_type n, const Allocator& = Allocator());
Preconditions: T is Cpp17DefaultInsertable into forward_list.
Effects: Constructs a forward_list object with n default-inserted elements using the specified allocator.
Complexity: Linear in n.
forward_list(size_type n, const T& value, const Allocator& = Allocator());
Preconditions: T is Cpp17CopyInsertable into forward_list.
Effects: Constructs a forward_list object with n copies of value using the specified allocator.
Complexity: Linear in n.
template<class InputIterator> forward_list(InputIterator first, InputIterator last, const Allocator& = Allocator());
Effects: Constructs a forward_list object equal to the range [first, last).
Complexity: Linear in distance(first, last).
template<container-compatible-range<T> R> forward_list(from_range_t, R&& rg, const Allocator& = Allocator());
Effects: Constructs a forward_list object with the elements of the range rg.
Complexity: Linear in ranges​::​distance(rg).
