Struct lamcal::ParseError

pub struct ParseError { /* fields omitted */ }

An error that occurs during parsing of expressions.

Methods

impl ParseError

pub fn new(     kind: ParseErrorKind,     position: CharPosition,     found: impl Display,     expected: impl Display,     hint: Option<Hint> ) -> Self

Constructs a new ParseError with the given information.

pub fn kind(&self) -> ParseErrorKind

Returns the kind of error that has been found.

pub fn position(&self) -> CharPosition

Returns the position in the input stream, where the error has been found.

pub fn found(&self) -> &str

Returns the slice of the expression which causes the error.

pub fn expected(&self) -> &str

Returns a description of what is expected to form a correct expression.

pub fn hint(&self) -> Option<&Hint>

Returns an additional hint for finding and fixing the error.

The hint is optional. So some errors might not have a hint for you.

Trait Implementations

impl Debug for ParseError

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

Formats the value using the given formatter.

impl Clone for ParseError

fn clone(&self) -> ParseError

Returns a copy of the value.

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

Performs copy-assignment from source.

impl PartialEq for ParseError

fn eq(&self, other: &ParseError) -> bool

This method tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &ParseError) -> bool

This method tests for !=.

impl Display for ParseError

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

Formats the value using the given formatter.
