ParseError is an enum which represents errors encounted during parsing an expression

Variants

Expected(Vec<TokenKind>, Token, Option<&'static str>)

When it expected a certain kind of token, but got another as part of something

ExpectedExpr(&'static str, Node, Position)

When it expected a certain expression, but got another

UnexpectedKeyword(Keyword, Position)

When it didn't expect this keyword

Unexpected(Token, Option<&'static str>)

When a token is unexpected

AbruptEnd

When there is an abrupt end to the parsing

RangeError

Out of range error, attempting to set a position where there is no token

General(&'static str, Option<Position>)

Catch all General Error
