operator== (std::ranges::take_view:: sentinel <Const>)

friend constexpr bool operator == ( const std:: counted_iterator < ranges:: iterator_t < Base >> & y, const /*sentinel*/ & x ) ;	(1)	(since C++20)
template < bool OtherC = ! Const > requires std:: sentinel_for < ranges:: sentinel_t < Base > , ranges:: iterator_t < /*add-const-if*/ < OtherC, V >>> friend constexpr bool operator == ( const std:: counted_iterator < ranges:: iterator_t < /*add-const-if*/ < OtherC, V >>> & y, const /*sentinel*/ & x ) ;	(2)	(since C++20)

Compares a take_view :: /*sentinel*/ with a std::counted_iterator (typically obtained from a call to take_view::begin ).

Returns true if y points past the N ^th element (where N is the number passed to the constructor of take_view ), or if end of underlying view is reached.

The exposition-only alias template /*add-const-if*/ is defined as
template < bool C, class T >
using /*add-const-if*/ = std:: conditional_t < C, const T, T > ; .

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

The != operator is synthesized from operator== .

Parameters

y	-	std::counted_iterator to compare
x	-	sentinel to compare

Return value

y. count ( ) == 0 || y. base ( ) == x. end_ , where end_ denotes the underlying sentinel.
