std::ranges::join_view<V>:: begin

constexpr auto begin ( ) ;	(1)	(since C++20)
constexpr auto begin ( ) const requires ranges:: input_range < const V > && std:: is_reference_v < ranges:: range_reference_t < const V >> ;	(2)	(since C++20)

Returns an iterator to the first element of the join_view . Given base_ is the underlying view,

Parameters

(none)

Return value

Iterator to the first element.

Notes

When ranges:: range_reference_t < V > is not a reference type, that is, deferencing an iterator of V returns a prvalue temporary, the join_view is only an input_range , in which case only single-pass iteration is supported, and repeated calls to begin() may not give meaningful results.
