SassCalculation
public final class SassCalculation: SassValueA Sass calculation value.
These correspond to Sass calc(), min(), max(), or clamp() expressions.
See the Sass docs.
The Sass compiler simplifies these before sending them to custom functions: this means that if you
receive a SassCalculation argument then it cannot be further simplified at compile time,
for example calc(20px + 30%).
The API here allows you to construct SassCalculations representing calc()-type expressions
including invalid ones such as calc(20px, 30px) as though you were writing a stylesheet. The
validity is checked – and the overall expression simplified – by the compiler when it receives the value.

enum Operator
Arithmetic operators valid within Value.operation(_:_:_:).

A subexpression of a SassCalculation.

Properties
var kind: Kind
var kind: Kind
var arguments: [Value]
var arguments: [Value]
The SassCalculation’s arguments. The Sass specification says how many
are actually valid for each Kind but this API does not check this.
Declaration
public let arguments: [Value]Misc
static func ==(lhs: SassCalculation, rhs: SassCalculation) -> Bool
static func ==(lhs: SassCalculation, rhs: SassCalculation) -> Bool
Two SassCalculations are equal if they have the same kind and arguments.
There’s no attempt at simplification here – so calc(10px) and calc(5px + 5px)
compare as different.
Declaration
public static func == (lhs: SassCalculation, rhs: SassCalculation) -> Boolfunc accept<V, R>(visitor: V) -> R
func accept<V, R>(visitor: V) -> R
Take part in the SassValueVisitor protocol.
Declaration
public override func accept<V, R>(visitor: V) throws -> R
