fn fmt(&self, fmt: &mut Formatter) -> Result

Formats the value using the given formatter.

impl<W, S, IA, IW, IS, E: ?Sized> EnvFuture<E> for Case<IA, IW, IS, E> where
    IA: Iterator<Item = PatternBodyPair<IW, IS>>,
    IW: IntoIterator<Item = W>,
    W: WordEval<E>,
    W::Error: IsFatalError,
    IS: IntoIterator<Item = S>,
    S: Spawn<E>,
    S::Error: From<W::Error> + IsFatalError,
    E: LastStatusEnvironment + ReportErrorEnvironment, 

type Item = ExitResult<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.
