Struct ParseError 

pub struct ParseError {
    pub message: String,
    pub span: Option<Span>,
    pub kind: ParseErrorKind,
    pub recoverable: bool,
}

A parse error with location and recovery information.

Fields

message: String

Human-readable error message

span: Option<Span>

Source location where the error occurred

kind: ParseErrorKind

Error categorization

recoverable: bool

Whether parsing can continue after this error

Implementations

impl ParseError

pub fn new(message: impl Into<String>, span: Option<Span>) -> Self

Create a new parse error.

pub fn unexpected_eof(span: Option<Span>) -> Self

Create an error for unexpected end of input.

pub fn unclosed_delimiter(delimiter: &str, span: Option<Span>) -> Self

Create an error for unclosed delimiters.

pub fn invalid_syntax(context: &str, span: Option<Span>) -> Self

Create an error for invalid syntax.

pub fn unknown_directive(directive: &str, span: Option<Span>) -> Self

Create an error for unknown directives.

pub fn with_kind(self, kind: ParseErrorKind) -> Self

Set the error kind.

pub fn non_recoverable(self) -> Self

Mark this error as non-recoverable.

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 Error for ParseError

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>)

🔬This is a nightly-only experimental API. (error_generic_member_access)

Provides type-based access to context intended for error reports.

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.
