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>
is an associated class of the arguments.
The !=
operator is synthesized from operator==
.
x | - | iterator to compare |
y | - | sentinel to compare |
y.end_ == x || !std::invoke(*y.pred_, *x)
, where end_
denotes the stored sentinel and pred_
denotes the stored pointer to predicate.
