Struct SpeculationGate 

pub struct SpeculationGate { /* private fields */ }

Decides whether a partial transcript revision is worth speculating on.

Two gates, both cheap: a debounce window, and a minimum amount of genuinely new content. Recognizers emit revisions far faster than retrieval can usefully run, and most revisions change nothing that would change the query.

Implementations

impl SpeculationGate

pub fn new(config: &TranscriptConfig) -> Self

Build a gate from transcript configuration.

pub fn reset(&mut self)

Reset between turns.

pub fn consider( &mut self, hypothesis: &TranscriptHypothesis, has_strong_signal: bool, now: Instant, ) -> SpeculationDecision

Decide whether to speculate on hypothesis at now.

A signal the deterministic extractor already recognised (a known entity, an explicit recall phrase) overrides both gates: those are exactly the cases where prefetching pays for itself.

Trait Implementations

impl Debug for SpeculationGate

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

Formats the value using the given formatter.
