expected: Vec<Term>

expected terminals

Implementations

impl<Term> InvalidTerminalError<Term>

pub fn backtrace<NonTerm>( parser: &impl GetParser<Term, NonTerm>, context: &impl GetContext<Term, NonTerm>, ) -> Vec<BTreeSet<ShiftedRuleRef>>

where NonTerm: PartialEq,

Generate backtrace information. This trace back on the state stack, and fetch the ruleset of each state. Each ruleset in the returned Vec contains every rule that the state was trying to parse, that is, only the rules with shifted > 0. 0’th index is the latest, that is, the last element of Vec will hold the initial state’s ruleset.

pub fn message(&self) -> String

where Term: Display,

Generate brief error message.

pub fn long_message<NonTerm>( &self, parser: &impl GetParser<Term, NonTerm>, context: &impl GetContext<Term, NonTerm>, ) -> String

where Term: Display + Hash + Eq, NonTerm: Display + PartialEq,

Generate long, detailed error message.

fn cause(&self) -> Option<&dyn Error>

👎Deprecated since 1.33.0: replaced by Error::source, which can support downcasting

fn source(&self) -> Option<&(dyn Error + 'static)>

Returns the lower-level source of this error, if any.

fn description(&self) -> &str
