NAME¶

deductionguidesforstd::ranges::take_view - deductionguidesforstd::ranges::take_view

Synopsis¶

Defined in header <ranges>
template< class R >
take_view( R&&, ranges::range_difference_t<R> ) -> (since C++20)
take_view<views::all_t<R>>;

The deduction guide is provided for std::ranges::take_view to allow deduction from
range and number of elements.

If R is a view, the deduced type is ranges::take_view<R>; otherwise, the deduced
type is usually ranges::take_view<ranges::ref_view<R>>.

Defect Reports

The following behavior-changing defect reports were applied retroactively to
previously published C++ standards.

DR Applied to Behavior as published Correct behavior
the template parameter R is R is unconstrained
LWG 3447 C++20 constrained with range (but range_difference_t requires
range)
