Returns an iterator to the first element of the chunk_view .

Let base_ denote the underlying view.
1) Available only if V models input_range . Equivalent to: 
current_ = ranges::begin(base_);
remainder_ = n_;
return __outer_iterator(*this);
current_ , remainder_ , and n_ are underlying exposition only data members of chunk_view .
2) Available if V models forward_range . Equivalent to: return iterator < false > ( this, ranges:: begin ( base_ ) ) ; , where iterator is exposition only nested class.
3) Available if V models forward_range . Equivalent to: return iterator < true > ( this, ranges:: begin ( base_ ) ) ; , where iterator is exposition only nested class.

Parameters

(none)

Return value

An iterator to the first element of the chunk_view , as described above.
