NAME¶

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

Synopsis¶

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

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.

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 bound_ with bound.

Non-member functions¶

In the following descriptions, value_ is an underlying 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, (since C++20)
const /*sentinel*/& y );

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) (1) (since C++20)

requires std::sized_sentinel_for<Bound, W>;
friend constexpr std::iter_difference_t<W>

operator-(const /*sentinel*/& x, const /*iterator*/& y) (2) (since C++20)

requires std::sized_sentinel_for<Bound, W>;

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.
