NAME¶

std::coroutine_handle::operatorbool - std::coroutine_handle::operatorbool

Synopsis¶

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.
