Struct ParseError

pub struct ParseError<P: Positioner> {
    pub position: P::Position,
    pub errors: Vec<Error<P>>,
}

Struct which hold information about an error that occured at a specific position. Can hold multiple instances of Error if more that one error occured at the position.

Fields

position: P::Position

The position where the error occured

errors: Vec<Error<P>>

A vector containing specific information on what errors occured at position

Implementations

impl<P: Positioner> ParseError<P>

pub fn new(position: P::Position, error: Error<P>) -> ParseError<P>

pub fn empty(position: P::Position) -> ParseError<P>

pub fn from_errors( position: P::Position, errors: Vec<Error<P>>, ) -> ParseError<P>

pub fn end_of_input(position: P::Position) -> ParseError<P>

pub fn add_message<S>(&mut self, message: S)

where S: Into<Info<P>>,

pub fn add_error(&mut self, message: Error<P>)

pub fn set_expected(&mut self, message: Info<P>)

pub fn merge(self, other: ParseError<P>) -> ParseError<P>

Trait Implementations

impl<P: Debug + Positioner> Debug for ParseError<P>

where P::Position: Debug,

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

Formats the value using the given formatter.

impl<P: Positioner + Display> Display for ParseError<P>

where P::Position: Display,

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

Formats the value using the given formatter.

impl<P> Error for ParseError<P>

where P: Positioner + Display + Debug + Any, P::Position: Display + Debug + Any,

fn description(&self) -> &str

👎Deprecated since 1.42.0: use the Display impl or to_string()

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

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

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.

impl<P: PartialEq + Positioner> PartialEq for ParseError<P>

where P::Position: PartialEq,

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

Tests for self and other values to be equal, and is used by ==.

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

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
