constexpr /*inner-iterator*/& operator++();	(1)	(since C++23)
constexpr void operator++( int );	(2)	(since C++23)

Increments the iterator.

Let parent_ be the underlying pointer to enclosing chunk_view.

1) Equivalent to:

++*parent_->current_;
if (*parent_->current_ == ranges::end(parent_->base_))
    parent_->remainder_ = 0;
else
    --parent_->remainder_;
return *this;

Before invocation of this operator the expression *this == std::default_sentinel must be false.

2) Equivalent to ++*this.

Parameters

(none)

Return value

1) *this

2) (none)
