std::coroutine_handle

Defined in header <coroutine>
template< class Promise > struct coroutine_handle;	(1)	(since C++20)
template<> struct coroutine_handle<void>;	(2)	(since C++20)

The class template coroutine_handle can be used to refer to a suspended or executing coroutine.

The behavior of a program that declares an explicit or partial specialization of coroutine_handle is undefined.

Member functions

(constructor)	constructs a coroutine_handle object (public member function)
operator=	assigns the coroutine_handle object (public member function)
Observers
done	checks if the coroutine has completed (public member function)
operator bool	checks if the handle represents a coroutine (public member function)
operator==operator<=> (C++20)	compares two coroutine_handle objects (function)
Control
operator()resume	resumes execution of the coroutine (public member function)
destroy	destroys a coroutine (public member function)
Promise Access
promise	access the promise of a coroutine (public member function)
Export/Import
address	exports the underlying address, i.e. the pointer backing the coroutine (public member function)
from_address [static]	imports a coroutine from a pointer (public static member function)
Hash Support
std::hash<std::coroutine_handle> (C++20)	specializes std::hash (class template specialization)
