§

OpenDelim(Delimiter)

An opening delimiter (e.g., {).

§

CloseDelim(Delimiter)

A closing delimiter (e.g., }).

§

Literal(TokenLitKind, Symbol)

A literal token.

Note that this does not include boolean literals.

Symbol is the literal’s parsed data. In string literals, this is the unescaped value, and excludes its quotes (", ') and prefix (hex, unicode).

§

Ident(Symbol)

Identifier token.

§

Comment(bool, CommentKind, Symbol)

A comment or doc-comment token.

Symbol is the comment’s data excluding its “quotes” (//, /**) similarly to symbols in string literal tokens.

§

Eof

End of file marker.
