get [static] |
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
.
