An error while lexing.

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.

Io(Error)

Available on crate feature std only.

IO error, in no_std environments this is a ()

InvalidUtf8(usize)

Invalid UTF-8 text at {0}

InvalidCharacter(usize)

invalid document character at {0}

UnexpectedEof(usize)

Unexpected end-of-file at {0}

BadEscline(usize)

Bad escline body at {0}

UnexpectedKeyword

Unexpected plain keyword

InvalidEscape(usize)

Invalid string escape at {0}

InvalidNumber

Invalid number value

BadUnicodeEscape(usize)

Bad unicode string escape at {0}

UnexpectedStringNewline(usize)

Unexpected newline in single-line string at {0}

BadRawString

Bad raw string start

MissingStringNewline

Missing newline after multi-line string start

BadEndString(usize)

Text before multi-line string end at {0}

BadIndent(Option<usize>)

Bad multi-line string indent at {0}

InvalidOperator

Invalid operator

MissingText

Missing expected text

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 PartialEq for LexerError

Don’t trust this impl :)

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