Errors that can arise during beam search.

Variants

EmptyBeams

No active beams remain.

BeamWidthMismatch

The number of beams in BeamStepInput does not match the state.

Fields

expected: usize

got: usize

VocabSizeMismatch

Vocabulary size in BeamStepInput does not match configuration.

Fields

expected: usize

got: usize

ZeroBeamWidth

beam_width is zero, which is invalid.

MaxLengthTooShort

max_length is too short to produce any output.

ScoringFunctionError(String)

The user-supplied scoring function returned an error.

InvalidTemperature(f64)

Temperature must be positive.

Trait Implementations

impl Clone for BeamSearchError

fn clone(&self) -> BeamSearchError

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for BeamSearchError

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

Formats the value using the given formatter.

impl Display for BeamSearchError

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

Formats the value using the given formatter.

impl Error for BeamSearchError

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.
