Enum LexerError 

pub enum LexerError {
    IncompleteInput,
    InvalidSymbol(u32, u32),
}

Errors that can occur during lexical analysis.

These errors are produced by the tokenizer when the input string contains invalid characters or ends unexpectedly.

Variants

IncompleteInput

The input ended unexpectedly while parsing a token.

This typically occurs when a string literal or other multi-character token is not properly closed.

InvalidSymbol(u32, u32)

An invalid character was encountered at the specified position.

The tuple contains (line_number, column_number).

Trait Implementations

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, __formatter: &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 Error

fn from(value: LexerError) -> Self

Converts to this type from the input type.

impl Serialize for LexerError

fn serialize<__S>(&self, __serializer: __S) -> Result<__S::Ok, __S::Error>

where __S: Serializer,

Serialize this value into the given Serde serializer.
