Enum LexerError 

pub enum LexerError {
    NoValidToken,
    UnclosedStringFormat(Span),
    UnclosedString(Span),
}

Possible errors encountered while tokenizing

Variants

NoValidToken

No valid token was found for the character

UnclosedStringFormat(Span)

A format string was encountered that wasn’t closed correctly

UnclosedString(Span)

A string was encountered that wasn’t closed correctly

Implementations

impl LexerError

pub fn kind(&self) -> &'static str

Get a descriptive name of the error type

impl LexerError

pub fn span(&self) -> Option<Span>

Get the span of the 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 Default for LexerError

fn default() -> LexerError

Returns the “default value” for a type.

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 PartialEq for LexerError

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