Struct conch_runtime::spawn::LocalRedirections

#[must_use = "futures do nothing unless polled"]
pub struct LocalRedirections<I, S, E: ?Sized, RR = RedirectRestorer<E>> where
    I: Iterator,
    I::Item: RedirectEval<E>,
    S: Spawn<E>,  { /* fields omitted */ }

A future representing the spawning of a command with some local redirections.

Trait Implementations

impl<R, I, S, E: ?Sized, RR> Debug for LocalRedirections<I, S, E, RR> where     I: Iterator<Item = R> + Debug,     R: RedirectEval<E>,     R::EvalFuture: Debug,     S: Spawn<E> + Debug,     S::EnvFuture: Debug,     RR: Debug,

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

Formats the value using the given formatter.

impl<R, I, S, E: ?Sized, RR> EnvFuture<E> for LocalRedirections<I, S, E, RR> where     R: RedirectEval<E, Handle = E::FileHandle>,     I: Iterator<Item = R>,     S: Spawn<E>,     S::Error: From<RedirectionError> + From<R::Error>,     E: AsyncIoEnvironment + FileDescEnvironment,     E::FileHandle: Clone + From<FileDesc>,     RR: RedirectEnvRestorer<E>,

type Item = 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.
