Enum EvaluationError 

pub enum EvaluationError {
    DepthExceeded {
        key: Box<EvaluationKey>,
    },
    FanoutExceeded {
        limit: NonZeroU32,
    },
}

Errors produced by the shared evaluation engine.

Variants

DepthExceeded

A recursive evaluation exceeded the configured depth limit.

Fields

key: Box<EvaluationKey>

Evaluation key that exceeded the limit.

FanoutExceeded

A single evaluator step exceeded the configured fanout limit.

Fields

limit: NonZeroU32

Configured fanout limit.

Trait Implementations

impl Clone for EvaluationError

fn clone(&self) -> EvaluationError

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for EvaluationError

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

Formats the value using the given formatter.

impl Display for EvaluationError

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

Formats the value using the given formatter.

impl Error for EvaluationError

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 From<EvaluationError> for EngineError

fn from(error: EvaluationError) -> Self

Converts to this type from the input type.

impl From<EvaluationError> for ZanzibarError

fn from(source: EvaluationError) -> Self

Converts to this type from the input type.

impl PartialEq for EvaluationError

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

Tests for self and other values to be equal, and is used by ==.

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

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
