Struct ParseError 

pub struct ParseError { /* private fields */ }

An error that occurs during parsing of expressions.

Implementations

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 Clone for ParseError

fn clone(&self) -> ParseError

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for ParseError

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

Formats the value using the given formatter.

impl Display for ParseError

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

Formats the value using the given formatter.

impl Fail for ParseError

fn name(&self) -> Option<&str>

Returns the “name” of the error.

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

Returns a reference to the underlying cause of this failure, if it is an error that wraps other errors.

fn backtrace(&self) -> Option<&Backtrace>

Returns a reference to the Backtrace carried by this failure, if it carries one.

fn context<D>(self, context: D) -> Context<D>

where D: Display + Send + Sync + 'static, Self: Sized,

Provides context for this failure.

fn compat(self) -> Compat<Self>

where Self: Sized,

Wraps this failure in a compatibility wrapper that implements std::error::Error.

impl PartialEq for ParseError

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