friend constexpr ranges:: range_difference_t < /*maybe-const*/ < OtherConst, /*InnerView*/ >>

operator - ( const /*sentinel*/ & y, const /*iterator*/ < OtherConst > & x ) ;
(2) (since C++23)

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 zip_transform_view:: sentinel is an associated class of the arguments.

Parameters

x - an iterator
y - a sentinel

Return value

Let inner_ denote the underlying iterator or sentinel respectively.

1) x. inner_ - y. inner_
2) y. inner_ - x. inner_
