std::UnsignedIntegral

From cppreference.com
< cpp‎ | concepts
Defined in header <concepts>
template < class T >
concept UnsignedIntegral = std::Integral<T> && !std::SignedIntegral<T>;
(since C++20)

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

Notes

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