operator==(ranges::enumerate_view::iterator, ranges::enumerate_view::sentinel )
template< bool OtherConst >
requires std::sentinel_for<
ranges::sentinel_t<Base>,
ranges::iterator_t</*maybe-const*/<OtherConst, V>>>
friend constexpr bool
operator==( const /*iterator*/<OtherConst>& x, const /*sentinel*/& y );
| (since C++23) |
Compares the underlying iterator of x with the underlying sentinel of y.
Let current_ denote the underlying iterator of x and end_ denote the underlying sentinel of y. Equivalent to:
return x.current_ == y.end_;.
This function template is not visible to ordinary unqualified or qualified lookup, and can only be found by argument-dependent lookup when enumerate_view::sentinel<Const> is an associated class of the arguments.
The != operator is synthesized from operator==.
Parameters
| x | - | an iterator to compare |
| y | - | a sentinel to compare |
Return value
The result of comparison.
