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

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>

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_
