template< bool OtherConst >

friend constexpr bool operator==( const /*iterator*/<OtherConst>& x,
const /*sentinel*/& y );
| (since C++20) |
Compares the underlying iterator of x with the underlying sentinel of y.
This function is not visible to ordinary unqualified or qualified lookup, and can only be found by argument-dependent lookup when elements_view::sentinel<Const> is an associated class of the arguments.
The != operator is synthesized from operator==.
| x | - | iterator to compare |
| y | - | sentinel to compare |
x.base() == y.base().
