common_view() = default;	(1)	(since C++20)
constexpr explicit common_view( V r );	(2)	(since C++20)

Constructs a common_view.

1) Default constructor. Value-initializes the underlying view. After construction, base() returns a copy of V()

2) Initializes the underlying view with std::move(r)

Parameters

r

-

underlying view to be adapted into a common-range
