Variants

EmptyQueryVector

Query vectors must be nonempty.

DimensionLimitExceeded

Vector dimensions exceed policy.

Fields

actual: usize

Observed dimension.

maximum: usize

Configured maximum.

DimensionMismatch

Candidate dimension differs from the query.

Fields

expected: usize

Query dimension.

found: usize

Candidate dimension.

NonFiniteVector

Query or candidate contains NaN or infinity.

ZeroVector

Cosine similarity is undefined for a zero vector.

EmptyCandidateKey

Candidate keys must be nonempty.

DuplicateCandidateKey

Candidate keys must be globally unique.

ZeroLimit

At least one result must be requested.

ResultLimitExceeded

Requested result count exceeds policy.

Fields

requested: usize

Requested count.

maximum: usize

Configured maximum.

InvalidMinimumScore

Minimum score is non-finite or outside cosine range.

InvalidMinimumMargin

Minimum margin is non-finite or outside cosine range width.

CandidateBudgetExceeded

Global candidate budget was exhausted.

Fields

maximum: u64

Configured maximum.

TimedOut

Cooperative monotonic deadline expired.

Trait Implementations

impl Clone for RetrievalError

fn clone(&self) -> RetrievalError

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for RetrievalError

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

Formats the value using the given formatter.

impl Display for RetrievalError

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

Formats the value using the given formatter.

impl Error for RetrievalError

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 PartialEq for RetrievalError

fn eq(&self, other: &RetrievalError) -> bool

Equality operator ==.

fn ne(&self, other: &Rhs) -> bool

Inequality operator !=.
