# operator==,<=>(ranges::enumerate_view::iterator)

From cppreference.com
< cpp‎ | ranges‎ | enumerate view‎ | iterator

friend constexpr bool operator==( const /*iterator*/& x, const /*iterator*/& y ) noexcept; | (1) | (since C++23)
friend constexpr std::strong_ordering operator<=>( const /*iterator*/& x, const /*iterator*/& y ) noexcept; | (2) | (since C++23)

Compares the underlying iterators. Let `pos_` be the underlying index.

1) Equivalent to return x.pos_ == y.pos_;.
2) Equivalent to return x.pos_ <=> y.pos_;.

These functions are not visible to ordinary unqualified or qualified lookup, and can only be found by argument-dependent lookup when `std::ranges::enumerate_view::iterator<Const>` is an associated class of the arguments.

The `<`, `<=`, `>`, `>=`, and `!=` operators are synthesized from operator<=> and operator== respectively.

### Parameters

x, y | - | iterators to compare

### Return value

Result of comparison.
