packaged_task& operator=(packaged_task&& other);
Transfer ownership of the asynchronous result and task associated
with other to
*this.
If *this
already had an associated asynchronous result, that asynchronous
result is made ready with an exception of
type std::future_error, and an error code
of std::future_errc::broken_promise.
The asynchronous result and task associated with other prior to the invocation
of the move-assignment operator is associated with the *this.
other has no associated
asynchronous result or task.
*this
Nothing.
