Enum ErrorCode 

#[non_exhaustive]
pub enum ErrorCode {
    PartitionUnresolved,
    PlacementMissing,
    PlacementBackendUnavailable,
    UnsupportedEndpoint,
    StaleEpoch,
    AuthFailed,
    Unauthorized,
    UpstreamFailed,
    Overloaded,
    CursorUnresolvable,
    PayloadTooLarge,
}

A stable, documented, machine-matchable error code.

Codes are part of the public contract: operators and LLMs match on them and look them up in the generated error reference. #[non_exhaustive] so new codes are additive (docs/08 §7).

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.

PartitionUnresolved

The partition could not be resolved from the request.

PlacementMissing

No placement exists for the resolved partition.

PlacementBackendUnavailable

The placement-lookup backend was unavailable.

UnsupportedEndpoint

The endpoint is not supported for tenancy rewriting in this mode.

StaleEpoch

A write was rejected because its stamped epoch is stale for a migrating partition (docs/06 §2). Retryable: the client re-resolves.

AuthFailed

Client authentication failed.

Unauthorized

The authenticated principal is not authorized for the action.

UpstreamFailed

The upstream cluster failed (timeout, reset, 5xx).

Overloaded

The proxy is shedding load.

CursorUnresolvable

A scroll/PIT cursor could not be resolved to its pinned cluster, its affinity envelope is missing, malformed, or unverifiable. The client must re-issue the originating search (docs/03 §6).

PayloadTooLarge

The request body exceeded a size cap (e.g. a single _bulk line over the per-op limit). A client error: the client must split or shrink the body.

Implementations

impl ErrorCode

pub fn as_slug(self) -> &'static str

A short, stable, machine-readable slug for logs and trace attributes.

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 Copy for ErrorCode

impl Debug for ErrorCode

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

Formats the value using the given formatter.

impl Display for ErrorCode

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

Formats the value using the given formatter.

impl Eq for ErrorCode

impl Hash for ErrorCode

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 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.
