| template < class T, class U > concept same_as = /* see below */; |
(since C++20) | |
The concept same_as<T, U> is satisfied if and only if T and U denote the same type.
std::same_as<T, U> subsumes std::same_as<U, T> and vice versa.
Possible implementation
namespace detail { template< class T, class U > concept SameHelper = std::is_same_v<T, U>; } template< class T, class U > concept same_as = detail::SameHelper<T, U> && detail::SameHelper<U, T>; |
