std::execution::seq, std::execution::par and std::execution::par_unseq are instances of the execution policy types std::execution::sequenced_policy, std::execution::parallel_policy and std::execution::parallel_unsequenced_policy respectively. They are used to specify the execution policy of parallel algorithms - i.e., the kinds of parallelism allowed.
Additional execution policies may be provided by a standard library implementation.
