Struct conch_runtime::eval::ast_impl::ComplexWord

#[must_use = "futures do nothing unless polled"]
pub struct ComplexWord<W, I, E: ?Sized> where
    W: WordEval<E>,
    I: Iterator<Item = W>,  { /* fields omitted */ }

A future representing the evaluation of a ComplexWord.

Trait Implementations

impl<W, I, E: ?Sized> Debug for ComplexWord<W, I, E> where     W: WordEval<E> + Debug,     W::EvalResult: Debug,     W::EvalFuture: Debug,     I: Iterator<Item = W> + Debug,

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

Formats the value using the given formatter.

impl<W, I, E: ?Sized> EnvFuture<E> for ComplexWord<W, I, E> where     W: WordEval<E>,     I: Iterator<Item = W>,

type Item = Fields<W::EvalResult>

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

type Error = W::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.
