Struct PosteriorDrawProvider 

pub struct PosteriorDrawProvider { /* private fields */ }

Draw-indexed posterior provider: one EmpiricalTableProvider per draw.

Implementations

impl PosteriorDrawProvider

pub fn new() -> Self

Empty posterior provider.

pub fn from_draws(draws: Vec<EmpiricalTableProvider>) -> Self

Construct from per-draw empirical tables.

pub fn len(&self) -> usize

Number of draws.

pub fn is_empty(&self) -> bool

Whether there are no draws.

Trait Implementations

impl Clone for PosteriorDrawProvider

fn clone(&self) -> PosteriorDrawProvider

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for PosteriorDrawProvider

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

Formats the value using the given formatter.

impl Default for PosteriorDrawProvider

fn default() -> PosteriorDrawProvider

Returns the “default value” for a type.

impl DistributionProvider for PosteriorDrawProvider

fn probability( &self, spec: &FactorSpec<'_>, assignment: &Assignment, ctx: &EvalContext, ) -> Result<f64, EvalError>

Probability / density mass for a factor under an assignment.

fn support( &self, vars: &[VariableId], ctx: &EvalContext, ) -> Result<Arc<[Arc<[Value]>]>, EvalError>

Discrete support for variables (cartesian rows of values aligned to vars).

fn outcome( &self, var: VariableId, assignment: &Assignment, ctx: &EvalContext, ) -> Result<f64, EvalError>

Outcome function value (identity: the bound value of var).

fn n_draws(&self) -> Option<usize>

Number of posterior draws, or None for a single empirical world.

fn quadrature( &self, _vars: &[VariableId], _ctx: &EvalContext, ) -> Result<Option<QuadratureNodes>, EvalError>

Optional continuous quadrature nodes (assignment_row, Lebesgue weight) for crate::ExprNode::IntegralOut.
