If T has a nested type executor_type, returns t.get_executor().
Otherwise returns type(). |
A program may specialise this traits type if the T
template parameter in the specialisation is a user-defined type. The template
parameter Executor
shall
be a type meeting the Executor requirements.
Specialisations shall meet the following requirements, where t
is a const reference to an object of
type T
, and e
is an object of type Executor
.
type
that identifies a type meeting the Executor requirements.

callable as get(t)
and with return type type
or a (possibly const) reference to type
.

,
callable as get(t,e)
and with return type type
