Error type for recall operations.

All variants implement CapabilityError for generic error handling.

Variants

IndexUnavailable

Index or vector store is temporarily unavailable.

Fields

message: String

Human-readable description of the unavailability.

DimensionMismatch

Query embedding dimensions don’t match index dimensions.

Fields

expected: usize

Expected dimension count.

got: usize

Actual dimension count from query.

EmbeddingFailed

Embedding operation failed (e.g., rate limited, timeout).

Fields

message: String

Human-readable error message.

transient: bool

Whether this failure is transient.

InvalidQuery

Query was malformed or invalid.

Fields

message: String

Description of what was invalid.

AuthFailed

Authentication with the recall backend failed.

Fields

message: String

Human-readable error message.

RateLimited

Rate limit exceeded; retry after delay.

Fields

retry_after: Duration

Suggested delay before retry.

Timeout

Operation timed out.

Fields

elapsed: Duration

How long the operation ran before timing out.

deadline: Duration

The configured deadline.

NotFound

Record not found for store/delete operation.

Fields

id: String

The ID that was not found.

Internal

Internal error with no specific category.

Fields

message: String

Human-readable error message.

Trait Implementations

impl CapabilityError for RecallError

fn category(&self) -> ErrorCategory

Returns the category of this error for generic handling.

fn is_transient(&self) -> bool

Returns true if the underlying condition may clear without changing the request.

fn is_retryable(&self) -> bool

Returns true if retrying the operation makes sense given typical idempotency.

fn retry_after(&self) -> Option<Duration>

Returns the suggested delay before retrying, if known.

impl Clone for RecallError

fn clone(&self) -> RecallError

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for RecallError

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

Formats the value using the given formatter.

impl Display for RecallError

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

Formats the value using the given formatter.

impl Error for RecallError

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
