(2) | (since C++23) |
Calculates the distance (in number of underlying elements) between the iterator and sentinel.
Let parent_
be the underlying pointer to the enclosing chunk_view
.
1) Equivalent to:
return ranges::min(i.parent_->remainder_,
ranges::end(i.parent_->base_) - *i.parent_->current_);
return ranges::min(i.parent_->remainder_,
ranges::end(i.parent_->base_) - *i.parent_->current_);
2) Equivalent to: return -(s - i);.
These functions are not visible to ordinary unqualified or qualified lookup, and can only be found by argument-dependent lookup when std::ranges::chunk_view::inner-iterator
is an associated class of the arguments.
