Enum RewriteError 

pub enum RewriteError {
    Rule {
        rule: RuleKey,
        kind: RuleError,
    },
    ContractViolation {
        target: RuleTargetKey,
        node_name: Option<String>,
    },
    MaxIterationsExceeded {
        max_iterations: usize,
    },
}

Top-level errors produced by the Rewrite phase.

Variants

Rule

An individual rule returned an error during application.

Fields

rule: RuleKey

kind: RuleError

ContractViolation

The output AST still contains a form that the rewrite contract requires to be eliminated.

Fields

target: RuleTargetKey

node_name: Option<String>

MaxIterationsExceeded

The Rewrite phase did not converge within the allowed iteration budget.

Fields

max_iterations: usize

Trait Implementations

impl Clone for RewriteError

fn clone(&self) -> RewriteError

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for RewriteError

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

Formats the value using the given formatter.

impl Display for RewriteError

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

Formats the value using the given formatter.

impl Eq for RewriteError

impl Error for RewriteError

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 RewriteError

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