Struct conch_runtime::eval::Error

#[must_use = "futures do nothing unless polled"]
pub struct Error<T, F> { /* fields omitted */ }

A future representing a Error parameter substitution evaluation.

Trait Implementations

impl<T: Debug, F: Debug> Debug for Error<T, F>

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

Formats the value using the given formatter.

impl<T, FT, F, E: ?Sized> EnvFuture<E> for Error<T, F> where     FT: StringWrapper,     F: EnvFuture<E, Item = Fields<FT>>,     F::Error: From<ExpansionError>,     E: VariableEnvironment,

type Item = Fields<T>

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

type Error = F::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.
