Variants§

§

InvalidArgument

The request contains invalid input (e.g., prompt exceeds context length).

§

CannotConnect

Failed to establish a connection to a remote worker.

§

Disconnected

An established connection was lost unexpectedly.

§

ConnectionTimeout

A connection or request timed out.

§

ResponseTimeout

The backend accepted the request but stopped responding (stream inactivity timeout).

§

Cancelled

The request was cancelled (e.g., client disconnected).

§

ResourceExhausted

The capacity constraint cannot be relieved by selecting another worker. This most commonly means the whole eligible worker pool is exhausted.

§

WorkerOverloaded

One selected worker is out of capacity while others may still have room. Distinct from Self::ResourceExhausted so a request whose routing constraints permit reassignment can migrate; both surface as HTTP 529.

§

Unavailable

No backend worker is currently available to handle the request.

§

WorkerUnavailable

One addressed worker answered that it does not serve this request’s endpoint instance (stale discovery or a worker shutting down) while other workers may. Distinct from Self::Unavailable so the request can migrate; both surface as HTTP 503.

§

Backend(BackendError)

Error originating from a backend engine.

§

InvalidRequest

The client request is malformed or fails request-level validation.

§

Unauthenticated

Authentication credentials are missing or invalid.

§

PermissionDenied

The authenticated caller is not permitted to perform the operation.

§

NotFound

The requested resource does not exist.

§

Conflict

The request conflicts with current resource state.

§

PayloadTooLarge

The request body exceeds a configured size limit.

§

UnsupportedMedia

The request uses an unsupported media type.

§

RateLimited

The caller exceeded an admission or request-rate limit.

§

CapacityExhausted

The eligible worker pool has no capacity.

§

BackendProtocol

A backend response violates the expected protocol.

§

DeadlineExceeded

The operation exceeded its deadline.

§

NotImplemented

The requested operation is not implemented.

§

Internal

An internal defect or unclassified failure occurred.

§

Unknown

Uncategorized or unknown error.

Implementations§

Source§

impl ErrorClass

Source

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

Return the canonical semantic class for a legacy or backend-specific variant.

Source

pub fn normalized(self) -> Self

Map a legacy or backend-specific variant to its canonical semantic class.

New producers should construct canonical classes directly. DynamoError::class applies this mapping after validating the class/reason identity and is the normal consumer entry point. Serialization also emits that validated canonical class, while retaining a compatible legacy representation during the migration window.
