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 and the delimiter.
2) Initializes the underlying view with std :: move ( base ) and the delimiter with std :: move ( pattern ) .
3) Initializes the underlying view with views:: all ( std:: forward < R > ( r ) ) and the delimiter with ranges:: single_view { std :: move ( e ) } .

Parameters

base - the underlying view (to be split)
pattern - view to be used as the delimiter
e - element to be used as the delimiter
