Returns

For a given expression E of type T, ranges::size(E) is equivalent to:

• +extent_v<T> if T is an array type.
• Otherwise, +E.size() if it is a valid expression and its type I models integral and disable_sized_range<std::remove_cvref_t<T>> is false.
• Otherwise, +size(E) if it is a valid expression and its type I models integral with overload resolution performed in a context that includes the declaration:

  template<class T> void size(T&&) = delete;

  and does not include a declaration of ranges::size, and disable_sized_range<std::remove_cvref_t<T>> is false.
• Otherwise, static_cast<U>(ranges::end(E) - ranges::begin(E)) where U is std::make_unsigned_t<iter_difference_t<iterator_t<T>>> if iter_difference_t<iterator_t<T>> satisfies integral and iter_difference_t<iterator_t<T>> otherwise; except that E is evaluated once, if it is a valid expression and the types I and S of ranges::begin(E) and ranges::end(E) model sized_sentinel_for<S, I> and forward_iterator<I>.
• Otherwise, ranges::size(E) is ill-formed.

Parameters

r

Returns

The result of calling ranges::data with a const-qualified (lvalue or rvalue) reference to r.

true if and only if range contains no elements.
