Typed rejection from the pure fusion seam.

Variants

InvalidAlpha(f64)

Alpha was NaN, infinite, or outside the closed unit interval.

NonFiniteScore

A raw score was NaN or infinite.

Fields

leg: FusionLeg

Affected leg.

rank: usize

Zero-based rank.

NegativeScore

Squared-L2 or BM25 was negative.

Fields

leg: FusionLeg

Affected leg.

rank: usize

Zero-based rank.

EstimatedVectorScore

The vector window still carried an estimated score.

Fields

rank: usize

Zero-based rank.

InvalidBounds

A bounded producer supplied a range its own window contradicts.

Fields

leg: FusionLeg

Affected leg.

detail: &'static str

Stable description of the violated bound.

UnrankedInput

A supposedly ranked input list changed score direction.

Fields

leg: FusionLeg

Affected leg.

rank: usize

Rank whose score violates the prior rank.

MissingDocumentIdentity

The caller could not map a leg-native id to the common identity.

Fields

leg: FusionLeg

Affected leg.

rank: usize

Zero-based rank.

DuplicateDocumentIdentity

Two candidates in one leg mapped to the same common identity.

Fields

leg: FusionLeg

Affected leg.

rank: usize

Zero-based rank of the duplicate.

Timeout

A leg timed out; partial hits are never returned.

Fields

partial: bool

Permanently false.

Cancelled

A leg was cancelled; partial hits are never returned.

Fields

partial: bool

Permanently false.

ReadCancelled

Store close cancelled a leg; partial hits are never returned.

Fields

partial: bool

Permanently false.

LegThreadStart

A Store-owned leg thread could not be created.

Fields

leg: FusionLeg

Leg whose required execution thread could not start.

detail: String

Stable operating-system error detail.

LegPanic

A Store-owned leg panicked and was contained at the join seam.

Fields

leg: FusionLeg

Leg that panicked.

detail: &'static str

Stable detail that never exposes an unwind payload.

Leg

A caller-owned leg failed before fusion.

Fields

leg: FusionLeg

Affected leg.

kind: LegFailureKind

Typed classification of the failure, so hosts do not parse detail.

detail: String

Stable caller-provided failure description.

Trait Implementations

impl Clone for FusionError

fn clone(&self) -> FusionError

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for FusionError

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

Formats the value using the given formatter.

impl Display for FusionError

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

Formats the value using the given formatter.

impl Error for FusionError

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
