Struct cedar_policy_core::evaluator::EvaluationError

pub struct EvaluationError { /* private fields */ }

An error generated while evaluating an expression

Implementations

impl EvaluationError

pub fn error_kind(&self) -> &EvaluationErrorKind

Extract the kind of issue detected during evaluation

pub fn source_loc(&self) -> Option<&Loc>

Extract the source location of the error, if one is attached

pub fn advice(&self) -> Option<&str>

Extract the advice attached to the error, if any

pub fn set_advice(&mut self, advice: String)

Set the advice field of an error

Trait Implementations

impl Clone for EvaluationError

fn clone(&self) -> EvaluationError

Returns a copy 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 Diagnostic for EvaluationError

fn help<'a>(&'a self) -> Option<Box<dyn Display + 'a>>

Additional help text related to this Diagnostic. Do you have any advice for the poor soul who’s just run into this issue?

fn source_code(&self) -> Option<&dyn SourceCode>

Source code to apply this Diagnostic’s Diagnostic::labels to.

fn labels(&self) -> Option<Box<dyn Iterator<Item = LabeledSpan> + '_>>

Labels to apply to this Diagnostic’s Diagnostic::source_code

fn code<'a>(&'a self) -> Option<Box<dyn Display + 'a>>

Unique diagnostic code that can be used to look up more information about this Diagnostic. Ideally also globally unique, and documented in the toplevel crate’s documentation for easy searching. Rust path format (foo::bar::baz) is recommended, but more classic codes like E0123 or enums will work just fine.

fn severity(&self) -> Option<Severity>

Diagnostic severity. This may be used by ReportHandlers to change the display format of this diagnostic.

fn url<'a>(&'a self) -> Option<Box<dyn Display + 'a>>

URL to visit for a more detailed explanation/help about this Diagnostic.

fn diagnostic_source(&self) -> Option<&dyn Diagnostic>

The cause of the error.

fn related<'a>( &'a self ) -> Option<Box<dyn Iterator<Item = &'a dyn Diagnostic> + 'a>>

Additional related Diagnostics.

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)>

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 ContextCreationError

fn from(source: EvaluationError) -> Self

Converts to this type from the input type.

impl From<RestrictedExprError> for EvaluationError

fn from(err: RestrictedExprError) -> Self

Converts to this type from the input type.

impl PartialEq for EvaluationError

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

This method tests for self and other values to be equal, and is used by ==.

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

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