Types

using sequenced_policy

^{Defined in header <futures/algorithm/policies.hpp>}

using sequenced_policy = std::execution::sequenced_policy;

Class representing a type for a sequenced_policy tag.

Description

This tag type is an alias to std::execution::sequenced_policy whenever it's available. Otherwise it's defined as an individual type.

using parallel_policy

^{Defined in header <futures/algorithm/policies.hpp>}

using parallel_policy = std::execution::parallel_policy;

Class representing a type for a parallel_policy tag.

Description

This tag type is an alias to std::execution::parallel_policy whenever it's available. Otherwise it's defined as an individual type.

using parallel_unsequenced_policy

^{Defined in header <futures/algorithm/policies.hpp>}

using parallel_unsequenced_policy = 
    std::execution::parallel_unsequenced_policy;

Class representing a type for a parallel_unsequenced_policy tag.

Description

This tag type is an alias to std::execution::parallel_unsequenced_policy whenever it's available. Otherwise it's defined as an individual type.

using unsequenced_policy

^{Defined in header <futures/algorithm/policies.hpp>}

using unsequenced_policy = std::execution::unsequenced_policy;

Class representing a type for an unsequenced_policy tag.

Description

This tag type is an alias to std::execution::unsequenced_policy whenever it's available. Otherwise it's defined as an individual type.

Attributes

variable seq

^{Defined in header <futures/algorithm/policies.hpp>}

constexpr sequenced_policy seq {};

Tag used in algorithms for a sequenced_policy.

variable par

^{Defined in header <futures/algorithm/policies.hpp>}

constexpr parallel_policy par {};

Tag used in algorithms for a parallel_policy.

variable par_unseq

^{Defined in header <futures/algorithm/policies.hpp>}

constexpr parallel_unsequenced_policy par_unseq {};

Tag used in algorithms for a parallel_unsequenced_policy.

variable unseq

^{Defined in header <futures/algorithm/policies.hpp>}

constexpr unsequenced_policy unseq {};

Tag used in algorithms for an unsequenced_policy.

variable is_execution_policy_v

^{Defined in header <futures/algorithm/policies.hpp>}

constexpr bool is_execution_policy_v = is_execution_policy<T>::value;

Determines whether T is a standard or implementation-defined execution policy type.

concept execution_policy

^{Defined in header <futures/algorithm/policies.hpp>}

template<class E>
concept execution_policy = is_execution_policy_v<E>;

Determines if a type is an execution_policy.
