std::corout...utine_handle(3)  C++ Standard Libary std::corout...utine_handle(3)

NAME
     std::coroutine_handle::coroutine_handle   -   std::coroutine_handle::corou-
     tine_handle

Synopsis
	constexpr coroutine_handle() noexcept;			     (1)  (since
     C++20)
	constexpr  coroutine_handle( std::nullptr_t ) noexcept;       (2) (since
     C++20)
	coroutine_handle( const coroutine_handle& other ) = default; (3)  (since
     C++20)
	coroutine_handle(  coroutine_handle&& other ) = default;      (4) (since
     C++20)

	Creates a coroutine_handle that does not refer a coroutine, or copies a
	coroutine_handle.

	1,2) Initializes the underlying address ptr to nullptr. After  construc-
     tion,
	address()  returns  nullptr,  and  the coroutine_handle does not refer a
     coroutine.
	These constructors are not declared for the specialization
	std::coroutine_handle<std::noop_coroutine_promise>.
	3,4) Copies the underlying address. The copy constructor and  move  con-
     structor are
	equivalent to implicitly declared ones.

Parameters
	other - another coroutine_handle to copy

Notes
	std::coroutine_handle<std::noop_coroutine_promise>  is	neither  default
     constructible
	nor constructible from std::nullptr_t. std::noop_coroutine can	be  used
     to create a
	new std::coroutine_handle<std::noop_coroutine_promise>.

	Static member functions from_promise and from_address can also create a
	coroutine_handle.
