Variants (Non-exhaustive)
This enum is marked as 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.
UnexpectedInput(String)
An unexpected symbol is encountered when tokenizing the script text.
UnterminatedString
A string literal is not terminated before a new-line or EOF.
StringTooLong(usize)
An identifier is in an invalid format.
MalformedEscapeSequence(String)
An string/character/numeric escape sequence is in an invalid format.
MalformedNumber(String)
An numeric literal is in an invalid format.
MalformedChar(String)
An character literal is in an invalid format.
MalformedIdentifier(String)
An identifier is in an invalid format.
ImproperSymbol(String, String)
Bad symbol encountered when tokenizing the script text.
