Struct Token 

pub struct Token(pub usize, pub Cow<'static, str>, pub usize);

Token value (lexeme).

The lexeme is stored as Cow<'static, str>: a keyword token whose source spelling matches its canonical form exactly (e.g. SELECT) borrows the associated &'static str from TokenType::as_str at zero cost, while every other token (identifiers, literals, differently-cased keywords, …) owns a freshly allocated String copied from the input.

Tuple Fields

0: usize

1: Cow<'static, str>

2: usize
