A grammar pass rejected its input grammar.

Variants

InvalidRepetitionRange

A repetition range with a negative lower bound, or an upper bound below the lower one.

Fields

lower: i64

The minimum repetition count.

upper: i64

The maximum repetition count, or -1 for unbounded.

FsmBuild(String)

A rule body could not be compiled into an automaton (e.g. an invalid regex).

LazyRuleBodyNotChoices

A lazy rule whose body is not a choices of terminal-like sequences.

Fields

rule_name: String

The name of the lazy rule.

LazyRuleElementNotTerminal

A lazy rule whose body contains an element that does not compile into the rule’s own FSM.

Fields

rule_name: String

The name of the lazy rule.

Trait Implementations

impl Clone for FunctorError

impl Eq for FunctorError

impl Error for FunctorError

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.
