[−][src]Enum rsass::sass::Value
A sass value.
Variants
Bang(String)
A special kind of escape. Only really used for !important.
Call(SassString, CallArgs)
A call has a name and an argument (which may be multi).
Literal(SassString)
List(Vec<Value>, ListSeparator, bool, bool)
A comma- or space separated list of values, with or without brackets.
Numeric(Number, Unit)
A Numeric value is a rational value with a Unit (which may be Unit::None) and flags.
Paren(Box<Value>)
"(a/b) and a/b differs semantically. Parens means the value should be evaluated numerically if possible, without parens / is not allways division.
Variable(String)
Color(Rgba, Option<String>)
Both a numerical and original string representation, since case and length should be preserved (#AbC vs #aabbcc).
Null
True
False
BinOp(Box<Value>, bool, Operator, bool, Box<Value>)
A binary operation, two operands and an operator. The boolean represents possible whitespace.
UnaryOp(Operator, Box<Value>)
Map(OrderMap<Value, Value>)
HereSelector
The magic value "&", exanding to the current selectors.
UnicodeRange(String)
A unicode range for font selections. U+NN, U+N?, U+NN-MM. The string is the entire value, including the "U+" tag.
