Enum TokenKind 

pub enum TokenKind {
    Keyword(Keyword),
    Ident,
    Int,
    Float,
    Char,
    Str,
    Punct(Punct),
    Eof,
}

What a token is.

Two bytes, so that a Token fits in sixteen. The categories that carry a value carry it in the token’s value field instead of in the variant, which is what keeps it that small.

Variants

Keyword(Keyword)

A keyword in this dialect.

Ident

An identifier, whose symbol is in Token::value.

Int

An integer constant, indexed by Token::value into Tokens::ints.

Float

A floating constant, indexed by Token::value into Tokens::floats.

Char

A character constant, indexed by Token::value into Tokens::chars.

Str

A string literal, indexed by Token::value into Tokens::strings. One token per run of adjacent literals, because that is one literal.

Punct(Punct)

A punctuator.

Eof

End of the translation unit.
