Description

get [static]

If T has a nested type cancellation_slot_type, returns t.get_cancellation_slot(). Otherwise returns type().

If T has a nested type cancellation_slot_type, returns t.get_cancellation_slot(). Otherwise returns s.

A program may specialise this traits type if the T template parameter in the specialisation is a user-defined type. The template parameter CancellationSlot shall be a type meeting the CancellationSlot requirements.

Specialisations shall meet the following requirements, where t is a const reference to an object of type T, and s is an object of type CancellationSlot.

  • Provide a nested typedef type that identifies a type meeting the CancellationSlot requirements.
  • Provide a noexcept static member function named get, callable as get(t) and with return type type or a (possibly const) reference to type.
  • Provide a noexcept static member function named get, callable as get(t,s) and with return type type or a (possibly const) reference to type.
