friend constexpr bool operator== ( const ranges::iterator_t <Base> & x,
const /*sentinel*/ & y ) ;
(since C++20)

Compares a take_while_view::/*sentinel*/ with an iterator into (possibly const-qualified) view V. The iterator is typically obtained from a call to take_while_view::begin

Returns true if x compares equal to the underlying sentinel of y (i.e. y.base()), or if the predicate returns false when applied to *x

This function is not visible to ordinary unqualified or qualified lookup, and can only be found by argument-dependent lookup when take_while_view::sentinel<Const>

The != operator is synthesized from operator==.

Parameters

x - iterator to compare
y - sentinel to compare

Return value

y.end_ == x || ! std::invoke ( *y.pred_, *x) , where end_ denotes the stored sentinel and pred_
