Struct Error

pub struct Error<Nt, T>
where
    Nt: NonterminalValue,
    T: TerminalValue,
{
    pub state: Vec<Symbol<Nt, T>>,
    pub kind: ErrorKind<Nt>,
}

Used as error variant for Result.

The reason for the error can be determined via the kind field.

Fields

state: Vec<Symbol<Nt, T>>

kind: ErrorKind<Nt>

Implementations

impl<Nt, T> Error<Nt, T>

where Nt: NonterminalValue, T: TerminalValue,

pub fn nonterm_expansion_failed( state: Vec<Symbol<Nt, T>>, expanded_nonterm_value: Nt, ) -> Self

pub fn max_iterations_reached( state: Vec<Symbol<Nt, T>>, iterations: usize, ) -> Self

Trait Implementations

impl<Nt, T> Debug for Error<Nt, T>

where Nt: NonterminalValue, T: TerminalValue,

impl<Nt, T> Error for Error<Nt, T>

where Nt: NonterminalValue, T: TerminalValue,

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>)
