Struct RuleGuidedBeamSearch

pub struct RuleGuidedBeamSearch { /* private fields */ }

Expand description

High-level composition of a beam-search decoder, a logical constraint and a masking strategy.

Implementations§

Source §

impl RuleGuidedBeamSearch

Source

pub fn new( config: BeamSearchConfig, constraint: RuleConstraint, masker: Arc<dyn LogitMasker>, ) -> Self

Construct a decoder with an explicit beam-search configuration.

Source

pub fn config(&self) -> &BeamSearchConfig

Read-only access to the underlying beam-search configuration.

Source

pub fn constraint(&self) -> &RuleConstraint

Read-only access to the compiled constraint.

Source

pub fn masker_name(&self) -> &'static str

Return the masker’s name ("HardMask" / "SoftPenaltyMask" / …).

Source

pub fn decode<F>( &self, bos_token_id: usize, score_fn: F, ) -> RuleGuidedResult<BeamSearchResult>
where F: Fn(&[&[usize]]) -> Result<Vec<Vec<f64>>, String>,

Run the decoder.

score_fn is the same “raw logits” closure accepted by BeamSearchDecoder::decode. The engine wraps it so that every row of the returned [num_beams][vocab_size] logit matrix is filtered through the configured LogitMasker before being passed on.
