Overloaded

Closing

Extractor

G11 (Slice 15) — BYO-LLM extractor subprocess error (protocol mismatch, spawn failure, or harness-returned error code).

InvalidFilter

G4 (Slice 35) — filter predicate construction error: non-allowlisted path or invalid filter argument. NOT a panic — returned as a typed error from Predicate::json_path_eq / Predicate::json_path_compare.

Fields

reason: String

InvalidArgument

Slice 20 (G5/G6) — an argument is out of the accepted range (e.g. depth > 3 for graph traversal). The msg field carries a human-readable explanation; it is intentionally non-exhaustive so the binding layer can forward it as a ValueError / TypeError.

Fields

msg: String

Trait Implementations

impl Clone for EngineError

fn clone(&self) -> EngineError

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for EngineError

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

Formats the value using the given formatter.

impl Display for EngineError

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

Formats the value using the given formatter.

impl Eq for EngineError

impl Error for EngineError

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 PartialEq for EngineError

fn eq(&self, other: &EngineError) -> 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.
