Struct BayesianUpdater 

pub struct BayesianUpdater { /* private fields */ }

Bayesian state updater for a single axis.

Maintains posterior distribution (mean, variance) and updates with each observation using standard Bayesian updating.

Implementations

impl BayesianUpdater

pub fn new() -> Self

Create a new updater with default configuration.

pub fn with_config(config: BayesianConfig) -> Self

Create an updater with custom configuration.

pub fn update( &self, axis: &str, prior: &Prior, observation: &Observation, ) -> AxisEstimate

Perform a Bayesian update given prior and observation.

Returns the posterior distribution as an AxisEstimate.

pub fn update_estimate( &self, existing: &AxisEstimate, observation: &Observation, ) -> AxisEstimate

Update an existing estimate with a new observation.

The existing estimate serves as the prior.

pub fn grow_uncertainty( &self, estimate: &AxisEstimate, elapsed_seconds: f64, ) -> AxisEstimate

Grow uncertainty over time without observations.

Variance increases linearly, representing growing uncertainty about stale estimates.

pub fn combine_observations( &self, axis: &str, prior: &Prior, observations: &[Observation], ) -> AxisEstimate

Combine multiple observations into a single posterior.

Useful when multiple signals about the same axis arrive at once.

Trait Implementations

impl Clone for BayesianUpdater

fn clone(&self) -> BayesianUpdater

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for BayesianUpdater

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

Formats the value using the given formatter.

impl Default for BayesianUpdater

fn default() -> BayesianUpdater

Returns the “default value” for a type.
