std::is_execution_policy(3)

Hey bestie! 💖 You’re looking at the std::is_execution_policy(3) page from the C++ Standard Libary manual — yes, that’s the manual name, typo and all, and we’re keeping it exactly as the source says. Slay. ✨

🌸 NAME 🌸

std::is_execution_policy - std::is_execution_policy

🌸 Synopsis 🌸

Defined in header <execution>
template< class T >            (since C++17)
struct is_execution_policy;

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 a standard execution policy type, or an implementation-defined execution policy type. Otherwise, value is equal to false.

⚠️ Undefined behavior alert: If the program adds specializations for std::is_execution_policy or std::is_execution_policy_v, the behavior is undefined. Not a vibe, bestie. 💀

🎀 Template parameters 🎀

• T — a type to check

🧚 Helper template 🧚

Defined in header <execution> — and yes, this one is since C++17 too. 🦋

template< class T >
inline constexpr bool is_execution_policy_v =
std::is_execution_policy<T>::value;

🧬 Inherited from std::integral_constant 🧬

💎 Member constants 💎

• value [static] — true if T is a standard or implementation-defined execution policy type, false otherwise (public static member constant)

🛠️ Member functions 🛠️

• operator bool — converts the object to bool, returns value (public member function)
• operator() — returns value (C++14) (public member function)

🧬 Member types 🧬

• value_type — bool
• type — std::integral_constant<bool, value>
