Struct LexerError 

pub struct LexerError {
    pub message: String,
    pub position: Position,
    pub limit_hit: Option<LexerLimitHit>,
}

Lexer error

Fields

message: String

Error message

position: Position

Position where error occurred

limit_hit: Option<LexerLimitHit>

Optional structured DoS-limit annotation. When set, the From<LexerError> for ParseError conversion preserves this kind so callers can pattern-match on the limit programmatically.

Implementations

impl LexerError

pub fn new(message: impl Into<String>, position: Position) -> Self

Create a new lexer error

Trait Implementations

impl Clone for LexerError

fn clone(&self) -> LexerError

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for LexerError

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

Formats the value using the given formatter.

impl Display for LexerError

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

Formats the value using the given formatter.

impl Error for LexerError

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 From<LexerError> for ParseError

fn from(e: LexerError) -> Self

Converts to this type from the input type.
