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_ .
2) Initializes bound_ with bound .

Non-member functions

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

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

Returns 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) Returns x. value_ - y. bound_ .
2) Returns - ( 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.
