Errors that can occur during indexing/search operations.

Variants

EmptyQuery

Empty query provided.

EmptyIndex

Empty index (no documents indexed).

InvalidParameter(String)

Invalid parameter value.

DimensionMismatch

Dimension mismatch between query and documents.

Fields

query_dim: usize

doc_dim: usize

InvalidSparseVector(String)

Invalid sparse vector (empty or malformed).

Io(String)

I/O error (wrapped)

OutOfBounds(usize)

Out of bounds access

FormatError(String)

Format error

Serialization(String)

Serialization error

Other(String)

Other error (for extensibility).

Trait Implementations

impl Clone for RetrieveError

fn clone(&self) -> RetrieveError

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for RetrieveError

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

Formats the value using the given formatter.

impl Display for RetrieveError

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

Formats the value using the given formatter.

impl Error for RetrieveError

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 RetrieveError

fn from(err: Error) -> Self

Converts to this type from the input type.

impl PartialEq for RetrieveError

fn eq(&self, other: &RetrieveError) -> 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.
