Enum cache_compute::Error

pub enum Error<E> {
    Broadcast(RecvError),
    Computation(E),
    Aborted(Aborted),
}

The error type for Cached.

E specifies the error the computation may return.

Variants

Broadcast(RecvError)

Notifying the other waiters failed with a RecvError. Either the inflight computation panicked or the Future returned by get_or_compute was dropped/canceled.

Computation(E)

The inflight computation returned an error value.

Aborted(Aborted)

The inflight computation was aborted

Trait Implementations

impl<E: Clone> Clone for Error<E>

fn clone(&self) -> Error<E>

Returns a copy of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl<E: Debug> Debug for Error<E>

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

Formats the value using the given formatter.

impl<E> Display for Error<E>where E: Display,

fn fmt(&self, __formatter: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl<E> Error for Error<E>where Self: Debug + Display,

fn source(&self) -> Option<&(dyn Error + 'static)>

The lower-level source of this error, if any.

fn description(&self) -> &str

👎Deprecated since 1.42.0: use the Display impl or to_string()

fn cause(&self) -> Option<&dyn Error>

👎Deprecated since 1.33.0: replaced by Error::source, which can support downcasting

fn provide<'a>(&'a self, demand: &mut Demand<'a>)

🔬This is a nightly-only experimental API. (error_generic_member_access)

Provides type based access to context intended for error reports.

impl<E> From<Aborted> for Error<E>

fn from(source: Aborted) -> Self

Converts to this type from the input type.

impl<E> From<RecvError> for Error<E>

fn from(source: RecvError) -> Self

Converts to this type from the input type.

impl<E: PartialEq> PartialEq<Error<E>> for Error<E>

fn eq(&self, other: &Error<E>) -> bool

This method tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

This method tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
