(parallelism TS) | |
Checks whether
T
is a standard or implementation-defined execution policy type.
Provides the member constant
value
which is equal to
true
, if
T
is
execution_policy
,
sequential_execution_policy
,
parallel_execution_policy
,
parallel_vector_execution_policy
, or an implementation-defined execution policy type. Otherwise,
value
is equal to
false
.
The behavior of a program that adds specializations for
is_execution_policy
is undefined.
