Errors produced by score aggregation and distance conversion operations.

Variants

LengthMismatch

The two input slices have different lengths.

Fields

expected_desc: &'static str

Human-readable description of which two slices were compared.

first_len: usize

Length of the first slice.

second_len: usize

Length of the second slice.

NonFiniteWeight

A weight at the given index is NaN or infinite.

Fields

index: usize

Zero-based index of the offending weight.

NonFiniteDistance

The distance value is NaN, +Inf, or -Inf.

InvalidDistanceRange

The distance is finite but outside the valid range for the metric.

Fields

metric_name: &'static str

The metric whose range was violated.

dist_bits: u32

Bit-representation of the out-of-range distance for diagnostics.

UnsupportedMetric

The distance metric is not one of the three currently supported variants.

Trait Implementations

impl Clone for ScoreError

fn clone(&self) -> ScoreError

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for ScoreError

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

Formats the value using the given formatter.

impl Display for ScoreError

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

Formats the value using the given formatter.

impl Eq for ScoreError

impl Error for ScoreError

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 ScoreError

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