Enum HedgeError 

pub enum HedgeError<E> {
    PrimaryFastError(E),
    PrimaryError(E),
    BackupError(E),
    Cancelled(CancelReason),
    Panicked(PanicPayload),
}

Error type for hedge operations.

When a hedge fails (winner has an error/cancel/panic), this type indicates which branch won and why it failed.

Variants

PrimaryFastError(E)

Primary completed fast with an error.

PrimaryError(E)

BackupError(E)

Backup won the race with an error.

Cancelled(CancelReason)

The winner was cancelled.

Panicked(PanicPayload)

The winner panicked.

Trait Implementations

impl<E: Clone> Clone for HedgeError<E>

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

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl<E: Debug> Debug for HedgeError<E>

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

Formats the value using the given formatter.

impl<E: Display> Display for HedgeError<E>

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

Formats the value using the given formatter.

impl<E: Debug + Display> Error for HedgeError<E>

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

Returns 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, request: &mut Request<'a>)
