template< bool OtherConst > requires (std::sentinel_for< ranges::sentinel_t</*maybe-const*/<Const, Views>>, ranges::iterator_t</*maybe-const*/<OtherConst, Views>>> && ...) friend constexpr bool operator==( const /*iterator*/<OtherConst>& x, const /*sentinel*/& y ); | (since C++23) |
Compares the underlying tuple of iterators of x
with the underlying tuple of sentinels of y
.
This function is not visible to ordinary unqualified or qualified lookup, and can only be found by argument-dependent lookup when zip_view::sentinel<Const>
is an associated class of the arguments.
The !=
operator is synthesized from operator==
.
x | - | iterator to compare |
y | - | sentinel to compare |
Let x.current_
denote the underlying tuple of iterators, and y.end_
denote the underlying tuple of sentinels.
Returns.
true
if at least one underlying iterator, obtained by expression equivalent to std::get<i>(x.current_)
, evaluates equal (using an appropriate operator==
) to some underlying sentinel, obtained by expression equivalent to std::get<i>(y.end_)
, for some index i
in ranges 0 <= i < sizeof...(Views)
, false
otherwise.
