NAME¶

std::ranges::lazy_split_view::begin - std::ranges::lazy_split_view::begin

Synopsis¶

constexpr auto begin(); (1) (since C++20)
constexpr auto begin() const
requires ranges::forward_range<V> && ranges::forward_range<const (2) (since C++20)
V>;

Returns an outer_iterator to the first element of the lazy_split_view.

Let base_ be the underlying view.

1) Equivalent to

constexpr auto begin() {
if constexpr (ranges::forward_range<V>)
return /*outer_iterator*/</*simple_view*/<V>>{*this, ranges::begin(base_)};
else {
current_ = ranges::begin(base_);
return /*outer_iterator*/<false>{*this};
}
}

2) Equivalent to return /*outer_iterator*/<true>{*this, ranges::begin(base_)};.

Parameters¶

(none)

Return value¶

outer_iterator to the first element.
