Failure to execute durable exact retrieval completely.

Variants

EmptyCandidateKey

Candidate keys must be nonempty.

DuplicateCandidateKey

Candidate keys must be unique in one space.

DimensionMismatch

Candidate and query dimensions must match.

Fields

expected: u16

Query dimension.

found: u16

Candidate dimension.

ZeroLimit

At least one match must be requested.

ResultLimitExceeded

The requested result count exceeds policy.

Fields

requested: usize

Requested result count.

maximum: usize

Maximum result count.

InvalidMinimumScore

The score threshold is outside the canonical cosine range.

InvalidMinimumMargin

The margin is outside the canonical cosine range width.

CandidateBudgetExceeded

The global candidate budget was exhausted.

Fields

maximum: u64

Maximum candidates.

CandidateByteBudgetExceeded

The aggregate candidate key/vector byte budget was exhausted.

Fields

maximum: u64

Maximum aggregate candidate bytes.

TimedOut

The cooperative timeout elapsed.

ArithmeticOverflow

Checked integer arithmetic failed.

Trait Implementations

impl Clone for ExactRetrievalError

fn clone(&self) -> ExactRetrievalError

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for ExactRetrievalError

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

Formats the value using the given formatter.

impl Display for ExactRetrievalError

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

Formats the value using the given formatter.

impl Eq for ExactRetrievalError

impl Error for ExactRetrievalError

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 ExactRetrievalError

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

Equality operator ==.

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

Inequality operator !=.
