std::ranges::take_while_view<V,Pred>::begin - cppreference.com (original) (raw)
Returns an iterator to the first element of the view. Effectively calls ranges::begin on the underlying view base_.
Overload (1) does not participate in overload resolution if V is a simple view (that is, if V and const V are views with the same iterator and sentinel types).
[edit] Parameters
(none)
[edit] Return value
ranges::begin(base_), where base_ is the underlying view.
