Struct TokenWithSpan

pub struct TokenWithSpan {
    pub token: Token,
    pub span: Span,
}

A Token with Span attached to it

This is used to track the location of a token in the input string

Examples

// commas @ line 1, column 10
let tok1 = TokenWithSpan::new(
  Token::Comma,
  Span::new(Location::new(1, 10), Location::new(1, 11)),
);
assert_eq!(tok1, Token::Comma); // can compare the token

// commas @ line 2, column 20
let tok2 = TokenWithSpan::new(
  Token::Comma,
  Span::new(Location::new(2, 20), Location::new(2, 21)),
);
// same token but different locations are not equal
assert_ne!(tok1, tok2);

Fields

token: Token

span: Span
