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

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

1) Equivalent to: return x. inner_ - y. inner_ ; .
2) Equivalent to: return y. inner_ - x. inner_ ; .

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

Parameters

x - the iterator
y - the sentinel

Return value

The distance between iterator and sentinel.
