Trait Implementations

impl<Alphabet: Debug> Debug for Error<Alphabet>

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

Formats the value using the given formatter.

impl<Alphabet> Display for Error<Alphabet>

where ExpectedTokenError<Alphabet>: Display,

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

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
