Struct CompiledEvaluator 

pub struct CompiledEvaluator { /* private fields */ }

Topologically ordered compiled evaluator for repeated provider evaluation.

Implementations

impl CompiledEvaluator

pub fn compile(arena: &CausalExprArena, root: ExprId) -> Result<Self, EvalError>

Compile an expression DAG into slot-addressed ops (post-order).

Continuous ExprNode::IntegralOut is supported (see CausalExprArena::compile).

pub fn evaluate( &self, arena: &CausalExprArena, provider: &dyn DistributionProvider, ctx: &EvalContext, ) -> Result<f64, EvalError>

Evaluate once against a provider.

Errors

Provider / numeric failures.

pub fn evaluate_with( &self, arena: &CausalExprArena, provider: &dyn DistributionProvider, ctx: &EvalContext, env: &Assignment, ) -> Result<f64, EvalError>

Evaluate with an initial variable binding (e.g. do(X=x) and outcome levels).

Errors

Provider / numeric failures.

pub fn evaluate_batch( &self, arena: &CausalExprArena, provider: &dyn DistributionProvider, ) -> Result<Vec<f64>, EvalError>

Evaluate over all posterior draws (provider.n_draws()), or a single empirical evaluation when n_draws is None.

Errors

Provider / numeric failures.

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

Performs copy-assignment from source.

impl Debug for CompiledEvaluator

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

Formats the value using the given formatter.
