Enum xxcalc::ParsingError

pub enum ParsingError {
    UnknownOperator(char, usize),
    UnexpectedToken(Token, usize),
    MissingBracket(usize),
    EmptyExpression,
}

An error that occurs during token processing, usually by a parser.

Variants

UnknownOperator(char, usize)

Encountered an operator which is not recognized by a parser. The operator is a first argument, while its position is the last one.

UnexpectedToken(Token, usize)

Encountered a Token with no meaning to the parser, probably a Token::Unknown. This token is a first argument, while its position is the last one.

MissingBracket(usize)

Detected a missing opening or closing bracket at given position.

EmptyExpression

Provided token list is empty, where expected it shouldn't be so.
