std::Same
From cppreference.com
| Defined in header <concepts>
|
||
| template < class T, class U > concept Same = /* see below */; |
(since C++20) | |
The concept Same<T, U> is satisfied if and only if T and U denote the same type.
std::Same<T, U> subsumes std::Same<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 = detail::SameHelper<T, U> && detail::SameHelper<U, T>; |
