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

WARNING

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(String)

An unexpected symbol is encountered when tokenizing the script text.

UnterminatedString

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

StringTooLong(usize)

An identifier is in an invalid format.

MalformedEscapeSequence(String)

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

MalformedNumber(String)

An numeric literal is in an invalid format.

MalformedChar(String)

An character literal is in an invalid format.

MalformedIdentifier(String)

An identifier is in an invalid format.

ImproperSymbol(String, String)

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

pub fn clone(&self) -> LexError

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for LexError

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

Formats the value using the given formatter.

impl Display for LexError

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

Formats the value using the given formatter.

impl Eq for LexError

impl Error for LexError

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

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

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

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

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

pub fn description(&self) -> &str

👎 Deprecated since 1.42.0:

use the Display impl or to_string()

pub fn cause(&self) -> Option<&dyn Error>

👎 Deprecated since 1.33.0:

replaced by Error::source, which can support downcasting

impl From<LexError> for ParseErrorType

pub fn from(err: LexError) -> Self

Performs the conversion.

impl Hash for LexError

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

Feeds this value into the given Hasher.

pub 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

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

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

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

This method tests for !=.
