Definiert im Header `<chrono>`
template < class Rep, class Period > struct hash < std:: chrono :: duration < Rep, Period >> ;		(seit C++26)

Die Template-Spezialisierung von std::hash für std::chrono::duration ermöglicht es Benutzern, Hashwerte von Objekten des Typs std:: chrono :: duration < Rep, Period > zu erhalten. Diese Spezialisierung ist aktiviert genau dann, wenn sowohl std:: hash < Rep > als auch std:: hash < Period > aktiviert sind.
