FutureInterface:: (2 methods):
  wait()
  cancel()


Interface: FutureInterface  - X-Ref

Represents the result of a computation that may not have completed yet.

You can use the future in a blocking manner using the wait() function, or
you can use a promise from the future to receive the result when the future
has been resolved.

When the future is dereferenced using wait(), the result of the computation
is cached and returned for subsequent calls to wait(). If the result of the
computation has not yet completed when wait() is called, the call to wait()
will block until the future has completed.
wait()   X-Ref
Returns the result of the future either from cache or by blocking until
it is complete.

This method must block until the future has a result or is cancelled.
Throwing an exception in the wait() method will mark the future as
realized and will throw the exception each time wait() is called.
Throwing an instance of GuzzleHttp\Ring\CancelledException will mark
the future as realized, will not throw immediately, but will throw the
exception if the future's wait() method is called again.

return: mixed

cancel()   X-Ref
Cancels the future, if possible.
