template< bool OtherConst >

requires std::sized_sentinel_for <ranges::sentinel_t <Base>,
ranges::iterator_t </*maybe-const*/<OtherConst, V>>>
friend constexpr ranges::range_difference_t </*maybe-const*/<OtherConst, V>>

operator-( const /*sentinel*/& y, const /*iterator*/<OtherConst>& x );

(2) (since C++20)

Computes the distance between the underlying iterator of x and the underlying sentinel of y.

These function templates are not visible to ordinary unqualified or qualified lookup, and can only be found by argument-dependent lookup when elements_view::sentinel is an associated class of the arguments.

[edit] Parameters

x - an iterator

y - a sentinel

[edit] Return value

1) x.base() - y.base()

2) y.base() - x.base()
