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.

UnexpectedCharacter(char)

A character could not begin or continue any token.

UnterminatedBlockComment

A nested block comment reached EOF before -}.

UnterminatedStringLiteral

A string literal reached EOF or newline before its closing quote.

UnterminatedStringGap

A string gap was opened but not closed correctly.

InvalidEscapeSequence(char)

A string or character escape used an unsupported escape code.

StraySingleQuote

A single quote did not form a valid character literal.

CharacterLiteralWrongLength

A character literal decoded to zero or multiple Unicode scalar values.

HexLiteralMissingDigits

A 0x/0X literal prefix was not followed by a hexadecimal digit.

DecimalExponentMissingDigits

A decimal exponent marker was not followed by exponent digits.

Trait Implementations

impl Clone for LexErrorKind

fn clone(&self) -> LexErrorKind

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for LexErrorKind

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

Formats the value using the given formatter.

impl Display for LexErrorKind

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

Formats the value using the given formatter.

impl Eq for LexErrorKind

impl PartialEq for LexErrorKind

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