Definiert im Header <stop_token>
template < class T, class CallbackFn >
using stop_callback_for_t = T :: template callback_type < CallbackFn > ;
(seit C++26)

Die Alias-Vorlage stop_callback_for_t wird verwendet, um den Stopp-Callback-Typ des Typs T zu erhalten.

Hinweise

Die entsprechenden stop_callback_for_t für Standard-Stopp-Token-Typen und jede gültige CallbackFn sind:

  • Spezialisierung von std:: stop_callback für std:: stop_token ,
  • Spezialisierung von std :: inplace_stop_callback für std :: inplace_stop_token , und
  • nicht spezifizierter Typ ohne Registrierung und Deregistrierung von Stopp-Callbacks für std :: never_stop_token .
