Constructors
UnexpectedToken Token | An error from the parser. Token found where it should not be. Note: tokens contain their own source span. |
UnexpectedChar Char SrcLocation | An error from the lexer. Character found where it should not be. |
StrError String | A generic error containing a string message. No source location. |
