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
.
