std::ranges::iota_view<W, Bound>::end

constexpr auto end() const;	(1)	(since C++20)
constexpr /iterator/ end() const requires std::same_as<W, Bound>;	(2)	(since C++20)

1) Obtains a sentinel representing the sentinel value:

If Bound is std::unreachable_sentinel_t, returns std::unreachable_sentinel.
Otherwise, returns sentinel {bound_ }.

2) Obtains an iterator to the sentinel value.

Return value

1) As specified above.

2) iterator {bound_ }

Example

#include <iostream>
#include <ranges>

int main()
{
    auto iota{std::views::iota(2, 6)};
    auto end{iota.end()};
    for (auto iter{iota.begin()}; iter != end; ++iter)
        std::cout << *iter << ' ';
    std::cout << '\n';
}

Output:

2 3 4 5
