Enum GuardError 

pub enum GuardError {
    Malformed(String),
    MissingVar(String),
    TypeError(String),
    FuelExceeded {
        limit: usize,
    },
    CustomOpFailed {
        op: String,
        source: String,
    },
}

Error returned by the high-level evaluate() tier.

Variants

Malformed(String)

Structural AST problem or unsupported operator.

MissingVar(String)

{"var": "X"} where X’s root key is absent from the data object. Detected via pre-walk; names the offending path explicitly.

TypeError(String)

Type coercion or argument-arity error from the evaluator.

FuelExceeded

In-loop node budget exhausted before evaluation completed.

Fields

limit: usize

CustomOpFailed

A registered custom operator returned Err(...).

Fields

op: String

source: String

Trait Implementations

impl Clone for GuardError

fn clone(&self) -> GuardError

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for GuardError

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

Formats the value using the given formatter.

impl Display for GuardError

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

Formats the value using the given formatter.

impl Eq for GuardError

impl Error for GuardError

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 GuardError

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

Equality operator ==.

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

Inequality operator !=.
