constexpr explicit lazy_split_view( R&& r, ranges::range_value_t <R> e ) ;
(3) (since C++20)

Constructs a lazy_split_view.

1) Default constructor. Value-initializes the underlying view base_ and the delimiter pattern_
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
