Defined in header <concepts>
template < class T > concept unsigned_integral = std::integral<T> && !std::signed_integral<T>;		(since C++20)

The concept unsigned_integral<T> is satisfied if and only if T is an integral type and std::is_signed_v<T> is false.

Notes

unsigned_integral<T> may be satisfied by a type that is not an unsigned integer type, for example, bool.
