Struct TokenInfo 

pub struct TokenInfo {
    token: Token,
    line: u32,
    col: u32,
}

A small wrapper around a Token that also contains line and column info. This just lets the lexer and parser output meaningful error messages so a user knows where a mistake may have been made.

Fields

token: Token

line: u32

col: u32
