Error type for rule operations

Encapsulates errors that can occur during rule loading, compilation, and evaluation.

Variants

LoadError(String)

Failed to load rules from a file or directory

InvalidRule(String)

Rule configuration is invalid

PatternError(PatternError)

Failed to compile a pattern through the matcher port

YamlError(Error)

Failed to parse YAML rule file

IoError(Error)

I/O error during file operations

DuplicateBuiltinRule

Two embedded built-in rule packs define the same rule id with divergent content. This is always a developer bug in the source YAML and must not be silently deduplicated at runtime.

Fields

id: String

first: String

second: String

DuplicateUserRule

A user-supplied rule pack declared a rule id that collides with an already-loaded rule. Only surfaced when strict mode is enabled.

Fields

id: String

path: String

ChecksumMismatch

External rule pack body’s SHA-256 digest does not match the value recorded in the <pack>.sha256 sidecar. The pack is rejected to prevent silently loading tampered rules.

Fields

path: String

expected: String

actual: String

MissingChecksum

External rule pack has no <pack>.sha256 sidecar and the engine is running with ChecksumPolicy::Required. Operators who want to load unsigned packs (development, ad-hoc tooling) can opt out via set_checksum_policy(ChecksumPolicy::Lenient) or ChecksumPolicy::WarnOnMissing.

Fields

path: String

Trait Implementations

impl Debug for RuleError

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

Formats the value using the given formatter.

impl Display for RuleError

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

Formats the value using the given formatter.

impl Error for RuleError

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.
