Errors from compiling or evaluating causal expressions.

Variants (Non-exhaustive)

Non-exhaustive enums could have additional variants added in future. Therefore, when matching against variants of non-exhaustive enums, an extra wildcard arm must be added to account for any future variants.

UnsupportedIntegralOut

Continuous IntegralOut without quadrature nodes and without discrete support.

MissingTableEntry

Provider has no entry for the requested factor / assignment.

MissingBinding(VariableId)

Required variable binding absent from the assignment.

EmptySupport(VariableId)

Provider reported empty support for a summed variable.

DivisionByZero

Division by zero while evaluating a ratio.

DrawOutOfRange

Posterior draw index out of range.

Fields

draw: usize

Requested draw.

n_draws: usize

Number of draws available.

SupportShape

Support row length does not match requested variable count.

Fields

expected: usize

Expected arity.

actual: usize

Actual arity.

ProviderKind(&'static str)

Empirical provider used where posterior draws are required (or vice versa).

UnsupportedConditioning(&'static str)

Provider cannot answer a conditional query (non-empty conditioned_on) — e.g. an independent-factor provider that only models unconditional marginals.

Trait Implementations

impl Clone for EvalError

fn clone(&self) -> EvalError

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for EvalError

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

Formats the value using the given formatter.

impl Display for EvalError

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

Formats the value using the given formatter.

impl Eq for EvalError

impl Error for EvalError

fn source(&self) -> Option<&(dyn Error + 'static)>

Returns the lower-level source of this error, if any.

fn description(&self) -> &str

👎Deprecated since 1.42.0:

use the Display impl or to_string()

fn cause(&self) -> Option<&dyn Error>

👎Deprecated since 1.33.0:

replaced by Error::source, which can support downcasting

fn provide<'a>(&'a self, request: &mut Request<'a>)

🔬This is a nightly-only experimental API. (error_generic_member_access)

Provides type-based access to context intended for error reports.

impl PartialEq for EvalError

fn eq(&self, other: &EvalError) -> bool

Equality operator ==.

fn ne(&self, other: &Rhs) -> bool

Inequality operator !=.
