drop_view() requiresstd::default_initializable<V>=default;	(1)	(since C++20)
constexprexplicit drop_view( V base,ranges::range_difference_t<V> count);	(2)	(since C++20)

Constructs adrop_view.

1) Default constructor.Value-initializes the underlying viewbase_ and initializes the countcount_ to0. After construction,base() returns a copy ofV() andsize() equals to the size of the underlying view.

2) Initializes the underlying viewbase_ withstd::move(base) and the countcount_ withcount. After construction,base() returns a copy ofbase andsize() returnsranges::size(base)- count if the size ofbase is not less thancount, or0 otherwise.

[edit]Parameters

base	-	the underlying view
count	-	number of elements to skip
