Returns an iterator to the first element of the chunk_view .

1) Available only if V models input_range . Equivalent to

current_ = ranges:: begin ( base_ ) ;
remainder_ = n_ ;
return outer_iterator ( * this ) ;

2) Available if V models forward_range . Equivalent to return iterator < false > ( this, ranges:: begin ( base_ ) ) ; .
3) Available if V models forward_range . Equivalent to return iterator < true > ( this, ranges:: begin ( base_ ) ) ; .

Return value

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