2) Initializes the underlying view base_ with std::move(base) and the delimiter pattern_ with std::move(pattern).
3) Initializes the underlying view base_ with views::all(std::forward<R>(r)) and the delimiter pattern_ with ranges::single_view{std::move(e)}.
Parameters
base - the underlying view to be split pattern - a view to be used as the delimiter e - an element to be used as the delimiter Example
