EmbedderNotConfigured

EmbeddingChangeRequiresAck

Attempted to change the database-wide embedding identity while enabled per-kind vector index schemas exist, but the caller did not acknowledge the rebuild impact. Re-invoke with acknowledge_rebuild_impact = true to proceed (which will mark the affected kinds stale without triggering a rebuild).

Fields

affected_kinds: usize

Number of enabled per-kind vector index schemas that would be marked stale by the identity change.

KindNotVectorIndexed

The caller ran semantic_search / raw_vector_search against a kind that has no enabled vector_index_schemas row. Configure per-kind vector indexing via AdminService::configure_vec_kind first.

Fields

kind: String

Node kind the caller tried to search.

DimensionMismatch

The caller’s vector (or the embedder’s output) does not match the active embedding profile’s dimension.

Fields

expected: usize

Dimension declared by the active embedding profile.

actual: usize

Dimension of the vector the caller / embedder produced.

Trait Implementations

impl Debug for EngineError

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

Formats the value using the given formatter.

impl Display for EngineError

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

Formats the value using the given formatter.

impl Error for EngineError

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

fn provide<'a>(&'a self, request: &mut Request<'a>)

🔬This is a nightly-only experimental API. (error_generic_member_access)

Provides type-based access to context intended for error reports.
