Canonical wire-level error code (RFC §18.2).

RATE_LIMITED is an alias for RESOURCE_EXHAUSTED per §18.2 and is represented by the same variant; the alias survives only at the deserialise boundary.

Variants (Non-exhaustive)

Non-exhaustive enums could have additional variants added in future. Therefore, when matching against variants of non-exhaustive enums, an extra wildcard arm must be added to account for any future variants.

Ok

OK — not an error; reserved.

Cancelled

CANCELLED

Unknown

UNKNOWN

InvalidArgument

INVALID_ARGUMENT

DeadlineExceeded

DEADLINE_EXCEEDED

NotFound

NOT_FOUND

AlreadyExists

ALREADY_EXISTS

PermissionDenied

PERMISSION_DENIED

ResourceExhausted

RESOURCE_EXHAUSTED (also serialised from the alias RATE_LIMITED).

FailedPrecondition

FAILED_PRECONDITION

Aborted

ABORTED

OutOfRange

OUT_OF_RANGE

Unimplemented

UNIMPLEMENTED

Internal

INTERNAL

Unavailable

UNAVAILABLE

DataLoss

DATA_LOSS

Unauthenticated

UNAUTHENTICATED

HeartbeatLost

HEARTBEAT_LOST (RFC §10.3)

LeaseExpired

LEASE_EXPIRED (RFC §15.5)

LeaseRevoked

LEASE_REVOKED (RFC §15.5)

BackpressureOverflow

BACKPRESSURE_OVERFLOW

BudgetExhausted

BUDGET_EXHAUSTED (ARCP v1.1 §12; §9.6)

LeaseSubsetViolation

LEASE_SUBSET_VIOLATION (ARCP v1.1 §9.4)

AgentVersionNotAvailable

AGENT_VERSION_NOT_AVAILABLE (ARCP v1.1 §12; §7.5)

Implementations

impl ErrorCode

pub const fn retryable(self) -> bool

Default retryability per RFC §18.3.

Errors flagged retryable here MAY still be rejected by application policy; conversely, errors flagged non-retryable MAY be retried by callers who know more than the protocol does. This method reports only the protocol’s default.

pub const fn as_str(self) -> &'static str

Wire-level string spelling of the code ("INVALID_ARGUMENT", etc.).

Trait Implementations

impl Clone for ErrorCode

fn clone(&self) -> ErrorCode

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for ErrorCode

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

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for ErrorCode

fn deserialize<__D>( __deserializer: __D, ) -> Result<ErrorCode, <__D as Deserializer<'de>>::Error>

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl Display for ErrorCode

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

Formats the value using the given formatter.

impl Hash for ErrorCode

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

where __H: Hasher,

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 ErrorCode

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

impl Serialize for ErrorCode

fn serialize<__S>( &self, __serializer: __S, ) -> Result<<__S as Serializer>::Ok, <__S as Serializer>::Error>

where __S: Serializer,

Serialize this value into the given Serde serializer.

impl Copy for ErrorCode

impl Eq for ErrorCode

impl StructuralPartialEq for ErrorCode
