[docs]defbind_future(function:Callable[[_FirstType],Future[_UpdatedType]],)->Kinded[Callable[[KindN[_FutureKind,_FirstType,_SecondType,_ThirdType]],KindN[_FutureKind,_UpdatedType,_SecondType,_ThirdType],]]:""" Compose a container and sync function returning ``Future``. In other words, it modifies the function signature from: ``a -> Future[b]`` to: ``Container[a] -> Container[b]`` Similar to :func:`returns.pointfree.lash`, but works for successful containers. This is how it should be used: .. code:: python >>> import anyio >>> from returns.pointfree import bind_future >>> from returns.future import Future >>> from returns.io import IO >>> def example(argument: int) -> Future[int]: ... return Future.from_value(argument + 1) >>> assert anyio.run( ... bind_future(example)(Future.from_value(1)).awaitable, ... ) == IO(2) Note, that this function works for all containers with ``.bind_future`` method. See :class:`returns.primitives.interfaces.specific.future.FutureLikeN` for more info.
