std::ranges::lazy_split_view<V,Pattern>::lazy_split_view

lazy_split_view()
  requires std::default_initializable<V> &&
           std::default_initializable<Pattern> = default;
 (1) (since C++20) 
constexpr explicit lazy_split_view( V base, Pattern pattern );
 (2) (since C++20) 
template< ranges::input_range R >
  requires std::constructible_from<V, views::all_t<R>> &&
           std::constructible_from<Pattern, ranges::single_view<
                                                ranges::range_value_t<R>>>
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
