type Item = ExitResult<SpawnedSimpleCommand<E::Future, S::Future>>

The type of value that this future will resolved with if it is successful.

type Error = S::Error

The type of error that this future will resolve with if it fails in a normal fashion.

fn poll(&mut self, env: &mut E) -> Poll<Self::Item, Self::Error>

Behaves identical to Future::poll when polled with a provided environment.

fn cancel(&mut self, env: &mut E)

Cancel a future and consider it as completed, thus giving it a chance to run any clean up as if it had resolved on its own.

fn pin_env(self, env: E) -> Pinned<E, Self> where
    E: Sized,
    Self: Sized, 

Pin an environment to this future, allowing the resulting future to be polled from anywhere without needing the caller to specify an environment.

fn fuse(self) -> Fuse<Self> where
    Self: Sized, 

Fuse a future such that poll and cancel will never again be called once it has completed.

fn boxed_result<'a>(self) -> BoxedResult<'a, Self> where
    Self: Sized,
    Self::Item: 'a + Future, 

Converts the resulting future into a boxed trait object.
