Enum CompilationError

pub enum CompilationError {
    Parse {
        rule: String,
        source: Box<dyn Error + Send + Sync>,

Available on crate feature validation only.

Errors that can occur during rule compilation.

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.

Parse

CEL expression failed to parse.

Fields

rule: String

The original CEL expression that failed to compile.

source: Box<dyn Error + Send + Sync>

The boxed parse error reported by the CEL compiler. Boxed (rather than carrying the concrete cel::ParseErrors) so the pre-1.0 cel type is not frozen into this public enum variant; reach it via Error::source.

MessageExpressionParse

A rule’s messageExpression failed to parse. The rule itself is well-formed, but its dynamic error message cannot be compiled. Surfaced as a compilation error (rather than silently dropped) so the rule fails closed, mirroring the apiserver, which rejects such a CRD at registration.

Fields

rule: String

The rule whose messageExpression failed to compile.

message_expression: String

The messageExpression that failed to compile.

source: Box<dyn Error + Send + Sync>

The boxed parse error reported by the CEL compiler. Boxed (rather than carrying the concrete cel::ParseErrors) so the pre-1.0 cel type is not frozen into this public enum variant; reach it via Error::source.

InvalidRule(Error)

JSON value could not be deserialized into a Rule.

SchemaTooDeep

Schema nesting exceeded the maximum depth. The over-deep subtree was refused rather than silently truncated, so a too-deep schema cannot quietly drop the validation rules nested beneath the cap (fail-closed).

Fields

depth: usize

The nesting depth at which the limit was exceeded.

Trait Implementations

impl Debug for CompilationError

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

Formats the value using the given formatter.

impl Display for CompilationError

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

Formats the value using the given formatter.

impl Error for CompilationError

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.
