Variants

UnclosedStringError

A string literal without the closing quote.

UnicodeError

MissingUnicodeLbrace

Missing the { for unicode escape sequence.

MissingUnicodeRbrace

Missing the } for unicode escape sequence.

IndentationError

The indentation is not consistent.

UnrecognizedToken

An unrecognized token was encountered.

Fields

tok: char

FStringError(InterpolatedStringErrorType)

An f-string error containing the InterpolatedStringErrorType.

TStringError(InterpolatedStringErrorType)

A t-string error containing the InterpolatedStringErrorType.

InvalidByteLiteral

Invalid character encountered in a byte literal.

LineContinuationError

An unexpected character was encountered after a line continuation.

Eof

An unexpected end of file was encountered.

OtherError(Box<str>)

An unexpected error occurred.

Trait Implementations

impl Clone for LexicalErrorType

fn clone(&self) -> LexicalErrorType

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for LexicalErrorType

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

Formats the value using the given formatter.

impl Display for LexicalErrorType

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

Formats the value using the given formatter.

impl Error for LexicalErrorType

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 GetSize for LexicalErrorType

fn get_heap_size(&self) -> usize

Determines how many bytes this object occupies inside the heap.

fn get_heap_size_with_tracker<TRACKER: GetSizeTracker>( &self, tracker: TRACKER, ) -> (usize, TRACKER)

Determines how many bytes this object occupies inside the heap while using a tracker.

fn get_stack_size() -> usize

Determines how may bytes this object occupies inside the stack.

fn get_size(&self) -> usize

Determines the total size of the object.

fn get_size_with_tracker<T>(&self, tracker: T) -> (usize, T)

where T: GetSizeTracker,

Determines the total size of the object while using a tracker.

impl PartialEq for LexicalErrorType

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