Typed failure from the two-stage rescore helper.

Variants

ZeroDimension

The declared dimension was zero.

QueryDimension

The query width differed from the declared row width.

Fields

expected: usize

Declared row width.

actual: usize

Supplied query width.

RowDataLength

The flat row matrix was not an exact multiple of the dimension.

Fields

dimension: usize

Declared row width.

actual: usize

Supplied scalar count.

CoarseScoreCount

The coarse score count differed from the matrix row count.

Fields

expected: usize

Number of matrix rows.

actual: usize

Supplied coarse score count.

CandidateRowCount

A retained graph pool supplied a different number of ids and scores.

Fields

expected: usize

Number of retained coarse scores.

actual: usize

Number of retained row ids.

CandidateRowOutOfRange

A retained graph-pool row id was outside the f32 matrix.

Fields

position: usize

Position inside the retained pool.

row_index: usize

Invalid stored row index.

row_count: usize

Available stored rows.

ZeroK

Exact top-k must request at least one hit.

ZeroOversample

Oversampling must retain at least k coarse candidates.

ZeroCandidateLimit

A per-segment candidate limit was zero.

CandidateLimitExceeded

The requested frontier or its boundary ties exceeded the explicit limit.

Fields

requested: usize

Candidate rows that would require exact scoring.

maximum: usize

Caller-supplied maximum per segment.

NonFiniteCoarseScore

A coarse score was NaN or infinite.

Fields

index: usize

Zero-based row position of the invalid score.

NonFiniteExactScore

Exact f32-row scoring produced NaN or infinity.

Fields

row_index: usize

Stored row whose exact score was invalid.

InsufficientCandidates

The supplied pool held fewer than k rows.

Fields

k: usize

Requested result count.

candidates: usize

Rows available for exact rescore.

ArithmeticOverflow

A candidate or byte-count multiplication overflowed usize.

Trait Implementations

impl Clone for RescoreError

fn clone(&self) -> Self

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for RescoreError

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

Formats the value using the given formatter.

impl Display for RescoreError

impl Eq for RescoreError

impl Error for RescoreError

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<RescoreError> for GraphSearchError

fn from(error: RescoreError) -> Self

Converts to this type from the input type.

impl PartialEq for RescoreError

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

Equality operator ==.

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

Inequality operator !=.
