Struct cedar_policy::ValidationError

pub struct ValidationError<'a> { /* private fields */ }

An error generated by the validator when it finds a potential problem in a policy. The error contains a enumeration that specifies the kind of problem, and provides details specific to that kind of problem. The error also records where the problem was encountered.

Implementations

impl<'a> ValidationError<'a>

pub fn error_kind(&self) -> &ValidationErrorKind

Extract details about the exact issue detected by the validator.

pub fn location(&self) -> &SourceLocation<'a>

Extract the location where the validator found the issue.

Trait Implementations

impl<'a> Clone for ValidationError<'a>

fn clone(&self) -> ValidationError<'a>

Returns a copy of the value.

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

Performs copy-assignment from source.

impl<'a> Debug for ValidationError<'a>

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

Formats the value using the given formatter.

impl<'a> Diagnostic for ValidationError<'a>

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

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

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

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

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

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<'s>(&'s self) -> Option<Box<dyn Display + 's>>

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

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

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

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

Additional related Diagnostics.

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

The cause of the error.

impl<'a> Display for ValidationError<'a>

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

Formats the value using the given formatter.

impl<'a> Error for ValidationError<'a>

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.
