Error types for the semantic-memory crate.

All errors flow through MemoryError, using #[from] for automatic conversion from rusqlite and reqwest errors.

Variants

Database(Error)

SQLite / rusqlite error.

EmbeddingRequest(Error)

HTTP error from the embedding provider.

DimensionMismatch

Embedding vector has wrong number of dimensions.

Fields

expected: usize

actual: usize

InvalidEmbedding

Raw BLOB data is not a valid embedding.

Fields

expected_bytes: usize

actual_bytes: usize

ModelMismatch

Database was created with a different embedding model.

Fields

stored: String

configured: String

SessionNotFound(String)

Session with the given ID does not exist.

FactNotFound(String)

Fact with the given ID does not exist.

DocumentNotFound(String)

Document with the given ID does not exist.

EmbedderUnavailable(String)

Embedding provider is unreachable or misconfigured.

MigrationFailed

Database migration failed.

Fields

version: u32

reason: String

HnswError(String)

HNSW index error.

InvalidKey(String)

Invalid HNSW key format.

QuantizationError(String)

Quantization error.

StorageError(String)

Storage path error.

IntegrityError

Index integrity check failed.

Fields

in_sqlite_not_hnsw: usize

in_hnsw_not_sqlite: usize

Other(String)

Catch-all for other errors.

Trait Implementations

impl Debug for MemoryError

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

Formats the value using the given formatter.

impl Display for MemoryError

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

Formats the value using the given formatter.

impl Error for MemoryError

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.

impl From<Error> for MemoryError

fn from(source: Error) -> Self

Converts to this type from the input type.

impl From<Error> for MemoryError

fn from(source: Error) -> Self

Converts to this type from the input type.
