The kind of error.

Variants

Cancelled

Operation was cancelled.

CancelTimeout

Cancellation cleanup budget was exceeded.

DeadlineExceeded

Deadline exceeded.

PollQuotaExhausted

Poll quota exhausted.

CostQuotaExhausted

Cost quota exhausted.

ChannelClosed

Channel is closed/disconnected.

ChannelFull

Channel is full (would block).

ChannelEmpty

Channel is empty (would block).

ObligationLeak

Obligation was not resolved before close/completion.

ObligationAlreadyResolved

Tried to resolve an already-resolved obligation.

RegionClosed

Region is already closed.

TaskNotOwned

Task not owned by region.

AdmissionDenied

Region admission/backpressure limit reached.

InvalidEncodingParams

Invalid encoding parameters (symbol size, block count, etc.).

DataTooLarge

Source data too large for configured parameters.

EncodingFailed

Encoding operation failed.

CorruptedSymbol

Symbol data is corrupted or invalid.

InsufficientSymbols

Not enough symbols received to decode.

DecodingFailed

Decoding operation failed (matrix singular, etc.).

ObjectMismatch

Symbol does not belong to the expected object.

DuplicateSymbol

Received duplicate symbol.

ThresholdTimeout

Decoding threshold not met within timeout.

RoutingFailed

Symbol routing failed (no route to destination).

DispatchFailed

Symbol dispatch failed.

StreamEnded

Symbol stream ended unexpectedly.

SinkRejected

Symbol sink rejected the symbol.

ConnectionLost

Transport connection lost.

ConnectionRefused

Transport connection refused.

ProtocolError

Transport protocol error.

RecoveryFailed

Region recovery failed.

LeaseExpired

Lease expired during operation.

LeaseRenewalFailed

Lease renewal failed.

CoordinationFailed

Distributed coordination failed.

QuorumNotReached

Quorum not reached.

NodeUnavailable

Node is unavailable.

PartitionDetected

Partition detected (split brain).

Internal

Internal runtime error (bug).

InvalidStateTransition

Invalid state transition.

ConfigError

Configuration error (invalid env var, bad config file, etc.).

User

User-provided error.

Implementations

impl ErrorKind

pub const fn category(&self) -> ErrorCategory

Returns the error category for this kind.

pub const fn recoverability(&self) -> Recoverability

Returns the recoverability classification for this error kind.

This helps retry logic decide whether to attempt recovery.

pub const fn is_retryable(&self) -> bool

Returns true if this error is typically retryable.

pub const fn recovery_action(&self) -> RecoveryAction

Returns the recommended recovery action for this error kind.

This provides more specific guidance than recoverability() about how to handle the error.

Trait Implementations

impl Clone for ErrorKind

fn clone(&self) -> ErrorKind

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for ErrorKind

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

Formats the value using the given formatter.

impl Hash for ErrorKind

fn hash<__H: Hasher>(&self, state: &mut __H)

Feeds this value into the given Hasher.

fn hash_slice<H>(data: &[Self], state: &mut H)

where H: Hasher, Self: Sized,

Feeds a slice of this type into the given Hasher.

impl PartialEq for ErrorKind

fn eq(&self, other: &ErrorKind) -> 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.
