Rejected barrier arrival.

Variants

UnknownParticipant

The participant is not in fixed membership.

Fields

participant: K

reply_to: Route

DuplicateArrival

The participant already arrived in this generation.

Fields

participant: K

Duplicate participant key.

generation: BarrierGeneration

Current barrier generation.

reply_to: Route

Exact release recipient from the rejected arrival.

StaleGeneration

Arrival belongs to a generation already released.

Fields

participant: K

Participant whose arrival was rejected.

observed: BarrierGeneration

Generation carried by the arrival.

current: BarrierGeneration

Current accepted generation.

reply_to: Route

Exact release recipient from the rejected arrival.

FutureGeneration

Arrival attempts to skip the current generation.

Fields

participant: K

Participant whose arrival was rejected.

observed: BarrierGeneration

Generation carried by the arrival.

current: BarrierGeneration

Current accepted generation.

reply_to: Route

Exact release recipient from the rejected arrival.

Exhausted

No representable successor generation remains.

Trait Implementations

impl<K: Clone, Route: Clone> Clone for BarrierError<K, Route>

fn clone(&self) -> BarrierError<K, Route>

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl<K: Debug, Route: Debug> Debug for BarrierError<K, Route>

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

Formats the value using the given formatter.

impl<K, Route> Display for BarrierError<K, Route>

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

Formats the value using the given formatter.

impl<K, Route> Error for BarrierError<K, Route>

where Self: Debug + Display,

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>)

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

Provides type-based access to context intended for error reports.

impl<K: PartialEq, Route: PartialEq> PartialEq for BarrierError<K, Route>

fn eq(&self, other: &BarrierError<K, Route>) -> bool

Tests for self and other values to be equal, and is used by ==.

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

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