requires std:: sized_sentinel_for < ranges:: sentinel_t < Base > ,

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.

Parameters

x - an iterator
y - a sentinel

Return value

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