<p>A Future interface.</p>
<p>Python doesn&#8217;t have a Future interface in its standard library. In the absence
of such a standard, three separate, incompatible implementations
(concurrent.futures.Future, ndb.Future, and asyncio.Future) have appeared. This
interface attempts to be as compatible as possible with
concurrent.futures.Future. From ndb.Future it adopts a traceback-object accessor
method.</p>
<p>Unlike the concrete and implemented Future classes listed above, the Future
class defined in this module is an entirely abstract interface that anyone may
implement and use.</p>
<p>The one known incompatibility between this interface and the interface of
concurrent.futures.Future is that this interface defines its own CancelledError
and TimeoutError exceptions rather than raising the implementation-private
concurrent.futures._base.CancelledError and the
built-in-but-only-in-3.3-and-later TimeoutError.</p>
