Variants§

§

Not(Box<SupportsCondition>)

not (condition)

§

Parenthesized(Box<SupportsCondition>)

(condition)

§

And(Vec<SupportsCondition>)

(condition) and (condition) and (condition) ..

§

Or(Vec<SupportsCondition>)

(condition) or (condition) or (condition) ..

§

Declaration(Declaration)

property-ident: value (value can be any tokens)

§

Selector(RawSelector)

A selector() function.

§

MozBoolPref(CString)

-moz-bool-pref("pref-name") Since we need to pass it through FFI to get the pref value, we store it as CString directly.

§

FontFormat(FontFaceSourceFormatKeyword)

font-format(<font-format>)

§

FontTech(FontFaceSourceTechFlags)

font-tech(<font-tech>)

§

FutureSyntax(String)

(any tokens) or func(any tokens)
