std::ranges::join_with_view<V,Pattern>:: begin

From cppreference.com

constexpr auto begin ( ) ;	(1)	(since C++23)
constexpr auto begin ( ) const requires ranges:: forward_range < const V > && ranges:: forward_range < const Pattern > && std:: is_reference_v < ranges:: range_reference_t < const V >> && ranges:: input_range < ranges:: range_reference_t < const V >> && /concatable/ < ranges:: range_reference_t < const V > , const Pattern > ;	(2)	(since C++23)

Returns an iterator to the beginning of the join_with_view .

1) Returns a mutable iterator or const iterator.

If V models forward_range , equivalent to constexpr bool use_const =
simple-view < V > && std:: is_reference_v < InnerRng > && simple-view < Pattern > ;
return iterator < use_const > { * this, ranges:: begin ( base_ ) } ; .
Otherwise, equivalent to outer_it_ = ranges:: begin ( base_ ) ;
return iterator < false > { * this } ; .

2) Returns a const iterator.

For the definition of


        
         
          concatable

1) As described above.

< true > { * this, ranges:: begin (


         
          
           base_
