(internals) Error encountered when tokenizing the script text. Exported under the internals feature only.

Volatile Data Structure

This type is volatile and may change.

Variants (Non-exhaustive)

Non-exhaustive enums could have additional variants added in future. Therefore, when matching against variants of non-exhaustive enums, an extra wildcard arm must be added to account for any future variants.

UnexpectedInput

An unexpected symbol is encountered when tokenizing the script text.

Tuple Fields of UnexpectedInput

0: String

UnterminatedString

A string literal is not terminated before a new-line or EOF.

StringTooLong

An identifier is in an invalid format.

Tuple Fields of StringTooLong

0: usize

MalformedEscapeSequence

An string/character/numeric escape sequence is in an invalid format.

Tuple Fields of MalformedEscapeSequence

0: String

MalformedNumber

An numeric literal is in an invalid format.

Tuple Fields of MalformedNumber

0: String

MalformedChar

An character literal is in an invalid format.

Tuple Fields of MalformedChar

0: String

MalformedIdentifier

An identifier is in an invalid format.

Tuple Fields of MalformedIdentifier

0: String

ImproperSymbol

Bad symbol encountered when tokenizing the script text.

Implementations

impl LexError

pub fn into_err(self, pos: Position) -> ParseError

Convert a LexError into a ParseError.

Trait Implementations

impl Clone for LexError

fn clone(&self) -> LexError

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for LexError

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

Formats the value using the given formatter.

impl Display for LexError

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

Formats the value using the given formatter.

impl Error for LexError

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

The lower-level source of this error, if any.

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

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

Returns a stack backtrace, if available, of where this error occurred.

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

impl From<LexError> for ParseErrorType

fn from(err: LexError) -> Self

Performs the conversion.

impl Hash for LexError

fn hash<__H: Hasher>(&self, state: &mut __H)

Feeds this value into the given Hasher.

fn hash_slice<H>(data: &[Self], state: &mut H) where
    H: Hasher, 

Feeds a slice of this type into the given Hasher.

impl PartialEq<LexError> for LexError

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

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

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

This method tests for !=.
