Struct BayesianBelief 

pub struct BayesianBelief { /* private fields */ }

Deterministic Bayesian state for one hypothesis.

Evidence is stored and replayed in EvidenceId order. Inserting the same set in a different arrival order therefore produces an identical posterior and audit trail. Reusing an evidence identifier replaces its likelihoods instead of double counting the observation.

Implementations

impl BayesianBelief

pub fn new(prior: Probability) -> Self

Starts a belief at the caller-supplied prior.

pub fn observe( &mut self, observation: BayesianEvidence, ) -> Result<BeliefWrite, ReasoningModelError>

Adds or replaces one observation and recomputes the posterior.

The operation is transactional: an undefined update leaves the belief unchanged.

pub fn prior(&self) -> Probability

Returns the initial probability before observations.

pub fn posterior(&self) -> Probability

Returns the current posterior probability.

pub fn evidence(&self) -> &[BayesianEvidence]

Returns observations in deterministic evidence-identifier order.

pub fn updates(&self) -> &[BayesianUpdate]

Returns every intermediate Bayesian update in evaluation order.
