struct /*sentinel*/;		(since C++20)

The return type of iota_view::end, used when the iota_view is bounded (i.e. Bound is not std::unreachable_sentinel_t) and Bound and W are not the same type.

The name of this class (shown here as /*sentinel*/) is unspecified.

Typical implementation holds one data member of type Bound (shown here as bound_), typically a number.

Member functions

std::ranges::iota_view::sentinel::sentinel

/*sentinel*/() = default;	(1)	(since C++20)
constexpr explicit /*sentinel*/( Bound bound );	(2)	(since C++20)

1) Value-initializes bound_ via its default member initializer (= Bound()).

2) Initializes exposition-only data member bound_ with bound.

Non-member functions

In the following descriptions, value_ is an exposition-only data member of iterator from which its operator* copies.

operator==(std::ranges::iota_view::iterator, std::ranges::iota_view::sentinel)

friend constexpr bool operator==( const /*iterator*/& x,                                   const /*sentinel*/& y );		(since C++20)

Equivalent to: return x.value_ == y.bound_;.

The != operator is synthesized from operator==.

This function is not visible to ordinary unqualified or qualified lookup, and can only be found by argument-dependent lookup when sentinel is an associated class of the arguments.

operator-(std::ranges::iota_view::iterator, std::ranges::iota_view::sentinel)

friend constexpr std::iter_difference_t<W>     operator-(const /*iterator*/& x, const /*sentinel*/& y)     requires std::sized_sentinel_for<Bound, W>;	(1)	(since C++20)
friend constexpr std::iter_difference_t<W>     operator-(const /*sentinel*/& x, const /*iterator*/& y)     requires std::sized_sentinel_for<Bound, W>;	(2)	(since C++20)

1) Equivalent to return x.value_ - y.bound_;.

2) Equivalent to return -(y.value_ - x.bound_);.

These functions are not visible to ordinary unqualified or qualified lookup, and can only be found by argument-dependent lookup when sentinel is an associated class of the arguments.
