std::experimental::ranges::Same (3) - Linux Manuals
std::experimental::ranges::Same: std::experimental::ranges::Same
NAME
std::experimental::ranges::Same - std::experimental::ranges::Same
Synopsis
Defined in header <experimental/ranges/concepts>
template < class T, class U > (ranges TS)
concept bool Same = std::is_same<T, U>::value; // see below
The concept Same<T, U> is satisfied if and only if T and U denote the same type.
Despite being specified using it, there need not be any subsumption relationship between Same<T, U> and std::is_same<T, U>::value.
For the purposes of constraint checking, Same<T, U> implies Same<U, T>.
Notes
The additional requirement on constraint checking differentiates Same from std::is_same.
