std::coroutine_handle
constexpr explicit operator bool ( ) const noexcept ;
(since C++20)

Checks whether *this is non-null, i.e. the value of *this is obtained from the promise object of some coroutine. Equivalent to return bool(address());

If Promise is std::noop_coroutine_promise, this conversion function always returns true

Parameters

(none)

Return value

bool(address()), or true if Promise is std::noop_coroutine_promise

 exports the underlying address, i.e. the pointer backing the coroutine
